I got shocked by engine ???

I got a 1971 F100 302

I put in a new thermostat, while it was running I put a screwdriver on the top hose to snug um down and the distributor gave me a shock ..about like an elec fence

That shouldn't do that??? Is it arching or what?

I'd guess bad ground from engine to frame... you were a better ground to the body?

time for a tune up

cap rotor wires are in poor shape if there leaking power

also place a film of dielectric grease around the rim of the cap when replacing to keep out moisture and prevent any further jolts.

also use it on both ends of the wires to keep the power in and water out

you probably got some coolant around and the power tracked across it

Some Beech, that was a rude awaking, makes this old mans toes curl thinking about it. All I can say, better thee than me.

its near imposable to diagnose a issue from a sound if your not standing there.

my experience with "zings" is a worn bushing causing contact or bad gear engagement on the cam.

drop one of these in there and forget about the ign system forever. Performance Distributors - High Performance and Racing Ignition Systems

i hope i dont get banned for pimping a chev product sorry mods

The distributor will not move is solid!

The sound is coming from inside the plastic cap..you can hear it great with a screw driver to your ear

If i put it below on the shaft you can BARLEY hear it...seems to me if it was bad gear engagement on the cam it would be loud on the shaft/neck below the cap

in the center of the cap there is a shaft that runs top to bottom supported by 2 bushings and spins verry fast
there is very tight tolerances within the distributor and you could be getting some contact causing the noise.

I replaced the plugs wires dist cap and rotor

The zinging is still there

But it stops when I unplug the vacuum hose that is hooked up to the closest port on that thing on the distributor. Idles higher and the zinging stops...

hmm

I would have posted sooner but the visual I have of the screw driver to your ear, and the earlier post of getting shocked Blew my stitches out and the Doc had to replace them. The phsychiatrist at the hospital could'nt get me to stop laughing so I had to stay there a couple of extra days. It was only then that I could draw a picture of a guy getting shocked.....then....putting the screw driver to his ear for yet another shock. Anyway sorry for the interruption. You guy's kill me!!!
