Just picked up a project HJ47 ute, put a new battery in, was starting and stopping on the key before xmas. Now no power in the cab (ign lights, nothing). Any ideas, only no auto-electrician handy here.

Replies appreciated,
Griff

renewed/cleaned and added a couple of extra earth straps - and guess what = POWER!

Only trouble now is the starter is rooted....

bench tested another starter - all good. Old one is stuffed - rebuild kit or not..

put good starter on vehicle - ignition lights in cab, 12.7 volts at battery, turn to start?

just the click of the edic arm going thru its motions - couldn't get a voltage read at the solenoid wire either?

what now? set up a manual start button? sorry for plain obvious questions here but really stuck where we are fro decent auto-electric knowledge. Are there any earths at the cab end that could require checking?

thanks, griff.

Without being intimate with an HJ47 (or any Toyota, for that matter) I don't know what access is like around your starter motor.

Can you bypass all the existing wiring, and use jumper cables direct between battery and starter motor? (Note: vehicle out of gear! :D ) Because it still sounds (to me) like a connection problem. If you can do this, experiment with the negative cable - try engine block as well as starter body.

What do you mean by "couldn't get a voltage read at the solenoid wire"? Could you not get a probe on the wire, or could you not measure a "sensible" voltage, or do you read an identical voltage whether "starting" or not?

If you disconnect your solenoid wire, and turn the key to "start", what voltage to you measure on the solenoid wire? Before "starting" and during?

Try measuring the voltage at either end of the heavy cable to your starter. Try to measure battery terminal to starter motor stud, rather than crimp lug to crimp lug - there could be a dodgy crimp connection.

Try measuring voltage between engine block/starter body and negative terminal during "starting" - measuring a few volts indicates you still have a dud connection somewhere.

Sorry if all the above has been tried - just throwing out ideas.

Good luck,

Scott

Worked!

Renewed heavy cable cleaned/new earth straps.

All OK - very satisfied. Now onto those other little jobs on this project...

Many thanks,
Griff.
