Re: Ignition Analyzer?

"Bill, thanks for the "tester" link. If I were working on
cars, I’d want one of those. If I get the gist of it,
it sounds like you compare voltages on the engines
different plug wires, weeding out the bad cylinder.
I suppose it may tell me which cylinder is acting
up on the Johnson, but I’m pretty sure it’s the
bottom one, as that spark plug was running cooler.
I’m coming to the conclusion that a Stevens type
tester that induces the arcing problem or coil
breakdown, which ever may be the case,
would be money better spent.
This Ebay ad explains the tool you mention in
case anyone else is interested…

Thanks!"

Well, I use it on outboards all the time. As long as the engine is running, it will tell you something…For instance, if your bottom cylinder is fouled, it would probably read around 2K, even though it’s not even firing. Normally you would see around 6-7K and if it were lean, it would be higher still. At any rate, even with just two cylinders, you would see an obvious difference if one was running and one wasn’t.

Long live American manufacturing!
