Was preparing for some further r&d this afternoon, installing an FSD harness set up with non-loading test points, and a remote-mount extension harness - length is not too important because it is a current-driver device, not a voltage-driver.

Pre-tested several FSD modules in heat-sink mounted and bare configurations to make sure all were functional.

Guess what?

Even tho the driver transistors are fairly well damped, it is possible to get quite a tingle while holding the bare module in one's hand with engine running - insulative black plastic covers having been discarded, earlier.

That was quite a shocker - involuntarily stimulating, to say the least.

And, yeah - the bare module proceeded to warm up rather quickly, sans heatsink.

More, later.............:cool:

Very interesting......:eek: :Whoa: :eyecrazy:

lol....how's the ticker?

Oh man, I feel your pain.
Never, ever have your hand on a Mallory magneto distributer and tell your buddy to fire it up for timing checks. Holly crap, I flopped under that hood like a live fish in a frying pan. 0to 3k rpm in a flat second man me hit my head repeatedly on the underside of the hood. Just not fun at all, whoever said that the rubber wire caps are good insulators need to do the ol' hand test :)

Wasn't near as bad as a Mallory - didn't soil me armor, or anything - I've been bit by 2cyl, 4cyl and 8cyl mag's, but of course I was much younger, then.

The ole ticker's back on schedule, and the urge to dribble is fading, so all's well that ends well
