I will asume the following:
Your battery is charged properly

What I would do

1. pull the plugs so the compression resistance is not there.
2. disconnect the BAT lead to the regulator this will take the charging
system out of the way.
3. try and turn over the engine as if you were starting it.
if it turns over nicely, check your plugs to see if their sparking.
4. if it does NOT turn over, hook a jumper to the + battery terminal and
jump the other end to the solenoid terminal, if it then turns over you
have a wiring issue between the starter button and the solenoid, if it
does NOT turn over you have a solenoid or starter problem.
5. if it did turn over in step 3, and you had spark, put the plugs back
in and try again, if it starts cool, if it turns over real slow, you
could have a battery or starter problem, or perhaps a severely advanced
timing situation.

This will check out the starter and ignition.

 Dave,

I'm seeking some electronic help and given that you are hard core
looper, perhaps you can help.

I'm restoring a 1972 Eldorado for a friend. I've done a ton of work and
the bike is starting to look great.

I'm having a wiring problem.

When I finished rebuilding the right cylinder, I fired the bike up and
it ran great.

However, I noticed a white spark near the voltage regulator when I
started the bike.

I shut the bike down to fix an oil leak

When I attempted to restart the bike, it turned over about 5 or 6 times
and stoped.

When this occured, I was DOA. Nothing. No lights anywhere and it was
basically dead.

Since then, I have traced the power throughout the bike.

I have juice going to the igniton switch and onward to the headlight
fuse panel.

All of the fuses are OK and I have juice going into the fuse panel and
out of the fuse panel.

I pulled the starter and had it checked. It hangs a little, but other
than that it turns great.

I replaced the starter relay switch.

I've check the grounds (battery and voltage regulator) and they look OK.

Got any ideas?

Would a fried voltage regulator cause this problem?

I'm stumped.

Thanks,

Joe Cox
