45 SS Runs on one cylinder when warmed up

[Dave M]

Thank You

On larger OMC you can OHM out the coils and power pack, always insure a positive ground to the plug, Sometimes even if you have spark in atmosphere, under compression and heat (warmed up) they break down or cause an open condition, as the other guys said, it is a sure way to spend $$$$

That is your answer you were seeking. He beat me to it as I typically only sign in at lunch time.

Where? It says nothing of WHAT it has to ground, short or touch to, to cause it to blow out. OHMing a PP is the LEAST reliable way to check a PP, but without a direct voltage adapter, it's all you got.

Thanks guys for the ideas! Unfortunately, I don’t have much free time this weekend (thanks honey) but I’ll try to get to these ideas ASAP.

Mark;
I found a coil test somewhere on the net. I’ll give it a go.

Howie;
Stator huh… I had a bad one on an old sea-flee motor in the seventies you may be right.

Trapper;
I ran a compression test so I think the head gasket is ok. I’ll try the other tests first.

ricochet112;
A friend lent me his “ignition spark tester” so I can check the spark without damaging the electronics. Also, I’ll try your PP test as soon as I get a chance.

Gardner Miller;
I think the compression test would have failed if the reeds were stuck open. If I don’t get anywhere with these other tests, I’ll try pulling the carb and having a look.

"Gardner Miller;

Even with a reed stuck open you can still have compression on that cylinder. What you won't have is crankcase pressure to force the intake charge to the cylinder causing it not to fire. When the piston comes down to pressurize the crankcase it will force the intake charge back out through the carb causing a "sneeze" through the carb every time the affected cylinder tries to run. I think though that I would start with the stator and if that checks out I would focus my attention to the power pack. I hope this helps.

dead cylinder

correct me if I'm wrong, why don't you just swap the plug wires,if your good cylinder goes bad and your bad cylinder becomes good, wouldn't that show that the "pp" might be the problem.

That is hysterical

This may have been seen by some prior but relates to holding onto plugs while testing. Use EXTREME CAUTION-Don't read with full bladder!!

Pocket Taser Stun Gun, a great gift for the wife.

Last weekend I saw something at Larry's Pistol & Pawn Shop that sparked my interest.

The occasion was our 32nd anniversary and I was looking for a little something extra for my wife Toni. What I came across was a 150,000-volt, pocket/purse-sized taser.
The effects of the taser were suppose to be short lived, with no long-term adverse affect on your assailant, allowing her adequate time to retreat to safety.... WAY TOO COOL!

Long story short, I bought the device and brought it home. I loaded two triple-a batteries in the darn thing and pushed the button. Nothing! I was disappointed. I learned, however, that if I pushed the button AND pressed it against a metal surface at the same time; I'd get the blue arch of electricity darting back and forth between the prongs. Awesome!!!

Unfortunately, I have yet to explain to Toni what that burn spot is on the face of her microwave.

Okay, so I was home alone with this new toy, thinking to myself that's it couldn't be all that bad with only two triple-a batteries... right?

There I sat in my recliner, my cat Gracie looking on intently (trusting little soul) while I was reading the directions and thinking that I really needed to try this thing out on a flesh & blood moving target. I must admit, I thought about zapping Gracie (for a fraction of a second) and thought better of it. She is such a sweet cat. But, if I was going to give this thing to my wife to protect herself
against a mugger, I did want some assurance that it would work as advertised. Am I wrong?

So, there I sat in a pair of shorts and a tank top with my reading glasses perched delicately on the bridge of my nose, directions in
one hand, taser in another. The directions said that a one-second burst would shock and disorient your assailant; a two-second burst was supposed to cause muscle spasms and a major loss of bodily control; a three-second burst would purportedly make your assailant flop on the ground like a fish out of water.
Any burst longer than three seconds would be wasting the batteries.

All the while I'm looking at this little device measuring about 5" long, less than 3/4 inch in circumference; pretty cute really and loaded with two itsy, bitsy triple-a batteries) thinking to myself, "no possible way!"

What happened next is almost beyond description, but I'll do my best.....

I'm sitting there alone, Gracie looking on with her head cocked to one side as to say, "don't do it master," reasoning that a one-second burst from such a tiny little ole thing couldn't hurt all that bad.... I decided to give myself a one-second burst just for the heck of it. I touched the prongs to my naked thigh, pushed the button, and

HOLY MOTHER, WEAPONS OF MASS DESTRUCTION @!@$$!%
mailto: DESTRUCTION @ ! @$$!%>!@*!!!

I'm pretty sure Jessie Ventura ran in through the side door, picked me up in the recliner, then body slammed us both on the carpet, over and over and over again.

I vaguely recall waking up on my side in the fetal position, with tears in my eyes, body soaking wet, both nipples on fire, testicles nowhere to be found, with my left arm tucked under my body in the oddest position, and tingling in my legs.

The cat was standing over me making meowing sounds I had never heard before, licking my face, undoubtedly thinking to herself, "do it again, do it again!
Note: If you ever feel compelled to "mug" yourself with a taser, one note of caution: there is no such thing as a one-second burst when you zap yourself. You will not let go of that thing until it is dislodged from your hand by a violent thrashing about on the floor. A three second burst would be considered conservative.

SON-OF-A-.... that hurt like hades!!! A minute or so later (I can't be sure, as time was a relative thing at that point), collected my wits
(what little I had left), sat up and surveyed the landscape.

My bent reading glasses were on the mantel of the fireplace. How did they get up here??? My triceps, right thigh and both nipples were still twitching. My face felt like it had been shot up with Novocain, and my bottom lip weighed 88 lbs. I'm still looking for my testicles? I'm offering a significant reward for their safe return.

Engine ignitions were fore runners to TASER Type devices!! RK

Did you know that 10 little Lithium 123 batteries will power an AED (Automated External Defibrillator) for 350 shocks! Guess this all proves there is no such thing as a little battery!

Does anyone have a wiring diagram for the 45 SS ignition?

[Tubby Nevada]

Had the same exact problem ran cold, but top cyl would die off when warm. I switched power packs, coils, wires, but the problem persisted and being an old Pro racer for like 150 years this stock stuff had me baffled. A kid with an A stock said make sure the coil ground bolts don't bottom out and put a star washer between the coil and the cast mounting stud. Gee I was red faced but it was fixed, youbetcha. Tubby

Well I went back up north last weekend. Pick up the boat and 45SS from the mechanic who was trying to help. Much to my surprise he claimed to have run it hard on the launch ramp with two timing lights hooked up, didn't notice anything and didn't have any issues. Other than cleaning out the top carb a bit more, he did nothing (he didn't find anything in the carb... he was just killing time and the ozone). His final comment was "runs fine for me..."

Huh...

Took it back to the cottage and did some checking anyway. The coils ohm'ed out just fine. Re-arranged some wires that might, and I say might, have been chaffing. The rectifier checked out fine too; zero ohms one way and infinity the other. The stator, however, seemed too low ohm wise. Then we ran the anti-Christ for a bit on the hose (can't beat the sound of open exhaust in the morning).

Then my sons and I tossed it in the lake and had great time burning gas Saturday and Sunday. The only thing is that we seem to have lost 5mph on the top end (and the engine doesn't quite crackle... you know, the angry sound a tuned up 45SS makes).

I'm going to replace the Stator on spec and see what that does (now that its running spending money makes sense again...). Howie you may be proven right soon...

Thanks all and I'll post anything else I find. Cheers,

DING DING DING!!! Thats what I was told by the local dealer when I had a similar problem & was asking about test equip. I switched the primary wires to find the other coill working so determining it to be the P-pack. Ive also had a coil that would run till warm, cool fairly quick during stall time & restart just to fail again a few later. This could probably be any of the other things listed. Good Luck
