alternater actin stupid...again

okhelp me figure this one out. My alt is puttin out like 15-16v at idle when i take the cable off the battery. If i put the cable back on then the motor lugs pretty bad and im not puttin out any voltage. just drawing off the battery and killing it. would a shorted cell in the battery do that? when i chek the battery engine off and the positive cable unhooked i get like 13.8v

whats going on here...and how do i get the alt to act normal and not put out that many volts.

p.s. its a stock 87 tin top with a 63amp GM alt.

Re: alternater actin stupid...again

I bet it's the DRIVER acting STOOOPID!!

GM alternator..
3 wires.
B+ stud to battery + terminal

Universal plugs have a red wire and a white wire.
red wire pigtail to the b+ stud.
white wire to idiot lamp, says to white/black wire

Re: alternater actin stupid...again

Disconnecting the battery cable while an internal regulated GM alternator is running will cause the rectifier bridge to grenade. This is a bad idea, and may have caused the results you are seeing.

Re: alternater actin stupid...again

yup.

some basic rules for jump starting - dont ever let the 2 vehicles touch, dont go battery to battery with the ground, dont just hook up &amp; crank - give it time to charge the dead battery a bit.

if you disconnected the battery cable with the engine running, and played with the revs at all, you can pretty much count on the GM being dead - rectifier, and regulator both.. the battery provides a load buffer for the alternator - disconnect it, and it'll give you max volts with minimum amps, frying the electronics instantly. (believe it or not, with no load they'll hit several hundred volts) Driving your rig withthe alt fried will kill the battery, even if it IS providing current, as it will over-charge, and boil the battery dry. You can also fry gauges, senders, bulbs, etc.

time for a rebuild kit, or a replacement alt.
