RE: [TriumphTrophy] Re: Frustrated in Florida!
- My only regret is that we didn't start there but it's nice to know
everything I know about the electrics now. My Dad ALWAYS started a tune up
or trouble shooting with the spark plug wires. However, back in the day, a
set of plugs, wires, rotor and distributor cap was less than $10! (;-)
Things have changed a bit!
A good friend has already offered up a good set of leads and I can
now get a few good nights sleep while I wait for them to get here. Thanks
for all your help and everyone else that pitched in. I was obviously getting
no where and going in the wrong direction before you stepped in to help.

AAAHHH HAA!! Now THAT is what I'm looking for. You should be getting around
5K ohms reading through motorbike leads. They have a built in 5K suppressor
(stops TV interferance etc.) Those suppressors often fail on high mileage
Don't forget the coils in these bike operate in series. Your lead #1 is OK
(although I'd still replace it) but lead #4 is bad so it may be just getting
enough energy to jump the spark through and fire the cylinder. However leads
#2 and #3 are both bad which would be a hard task for the coil to jump a
spark through both bad leads. Your symptoms remain consistent with what you
When leads go like that you can get exactly those symptoms. If they're open
circuit like that they may fire only every now and then (spark jump) but
when you are trying to start the engine it needs every spark it can find to
get things turning. When you rev the engine often the spark jumps enough to
fire the cylinders.
I think you have found your problem. CONGRATULATIONS!!
First thing to do is try and find a good set of leads which measure up the
correct resistance, maybe someone on the Forum over there can help??
Your almost on your way (and I'll bet it goes like a beauty, everything else
has been fixed ;^))
Regards and congrats in advance
