Alternator question
Still not right. Starts after releasing key from "start" position. Turns over in "start" but wont fire.
Heres tests while it was running.
12.83 Batt V
Alternator batt stud to ground 13.4V (bounces) at idle.
10.67V at VR FLD a idle. Volts go up with rpm.
Alternator batt stud to ALT case 14.14V
Above tests were done with it running.
More tests
Key off. 12.75 Batt voltage
Alternator batt stud to batt -ve 12.72V
Key on vehicle off
VR IGN to ground 10.4V
VR FLD to ground 9.53V
FLD terminal on alternator(again 1 wire alt) to ground 12.03V
I bought a Reman square back alt(used 73 340 Duster for application).
I also have a new BWD coil(again 73 application).
2 cheap ECUS are on their way. I'm prepared to buy better ones if recommended or once I figure out what the.problem is??
Also replaced pickup coil in distributor as one wire bared.
Suggestions?
Thanks
Steve
