Datsun 720 pickup
My 82 720 pickup is having an electric problem! I've
replaced the alternator 4 times and my battery light still
comes on and kills my battery eventually. The voltage
regulator is built into the alternator so I don't think it's that
the alternator passed the test at the shop. Help!
Sound like you have a shorted out battery. When the vehicle is running put a volt meter across the battery to see if there is 14.7 DCV. It there is then the alternator is working.
The alternator is good but when I hook that up its not jumping up when I crank it which would seem the alternator is bad but maybe a wire somewhere?
You never know, but I would have the battery tested.
Ok thanks so much
Got new battery and my battery lite still on
Have the alternator load check to see if it putting out enough volts...
