Construction and Road Equipment repair questions? Ask a mechanic ASAP
good afternoon my name is ***** ***** I can help you. have you checked the diode that is connected to the alternator with an ohm meter?
awesome but did you test the external diode? its connected to the alternator wrapped in a black plastic cover. 3 wire
so the 452 yellow wire has no power correct?
I suggest testing the F1 fuse
the K4 accessory relay
swap relay with one next to it and retest
and the relay??
test for 12 volt at the key switch wire 550 (yellow/white)
pin 30 on K4 relay wire 445 yellow 12 volt power. the relays are next to the fuse block (lift the cab) and you should see them
k4 is the relay furthest back of the 3 to the rear of the machine. k1 being the one closest to the front. relay is a small square box looking part
test light only. you need resistance on the circuit for a good reading and multi testers don't offer that
I'm here for a couple more hours
was it pin 30 that had power on K4?
did you test wire 550 at the key switch?
how did you make out?
