Got te dreaded low volt light today. Made it home on battery power only tg.

Swapped in an ad244. Seems to work for now.

Had to get a longer belt and a 3" 3/8 bolt and nut. Had the plug already and resistor for excite wire. Wired up a sense wire to distribution block.

Got in an overdrive alternator pulley 49mm. I was able to go back to the stock size belt, its on the tight side, but there is still adjustment left in the tensioner, and the belt is nearly brand new so it'll likely stretch a tiny bit. Was able to return the bigger belt, so it was actually cheaper to get an overdrive pulley. Considering the rpm range of the tbi is like 500-4000 rpms I doubt I will see any disadvantage of running the overdrive pulley.

Volts sit right on 14v on the gauge @ idle now with max a/c and (stock) stereo cranked & lights on. Before I was seeing >12v.

Damn ICM is crapping out again. Its only been like 1000 miles. It dies if I let it sit and idle in 100+*F

Ponied up for the ACDelco and MX5 this time. Do people not relocate these things on these rigs? Seems like a major weak point on the TBI trucks
