I have a 1993 toyota pick up with a 22re 5spd. I am having trouble getting it to charge. I took the alternator in to have it tested and it test fine, but on the truck it only reads 12.6 volts at the battery. If I unplug the alternator connection, My little volt meter will read 13.7 volts, but if I plug it back into the truck and test through the wires, it drops to 12.6 on the truck side of the plug. Any Ideas?? Thanks

 

maybe time for some new battery cables? how many amps. is putting out? thats the real question. amps is whats charging the battery.

 

I have just put brand new cables, ground strap and battery in it. If I unhook a calbe the truck dies.
