Thread: Burning out Chevy HEI Ignition modules

Tweet

I did check the altinater out put, and it is puting out 14.5 volts I also bought a new mod. from Jegs to put in to get the wells unit out of there. I also bought a ground strap and will be putting it on. I think I am going to keep the cheap wells unit as a just in case! I will let you guys know if any other problem comes of this. I eally thank everybody's imput. Thanks Steve. New e-mail address srsv8dime@bellsouth.net

i personally dont like telling people to check for amperage unless i know they know what they're doing... too many times have i asked someone to check amperage and they dont hook it up in series, and next thing you know they blew my fuse in my meter and fry some electrical in the vehiclel.

good idea.... kinda like i used to keep a spare set of points in my galaxie.... fords always fuse points which can really be a problem

((fords always fuse points which can really be a problem)). Only true if the system is not set up correctly.

yup like using too hot of a coil and cheap points... which is what a lot of people do... including me until i upgraded to electronic ignitions one by one on my cars... i've only got one that still runs points and its one i stuck an engine i found laying around in and am planning on selling....

and yes of course amperage wont be correct with 16 volts because the resistances aren't changing.... but incorectly testing for amperage is a good way to let the smoke out of your wiring
