taco stoped working

i have thought of that but not sure. mainly thought it might be a bad earth, cause the taco is meant to have a earth wire that runs to ground, not on ECM common return, any idea how i can work out which wire at the back of taco is the earth wire?

 

i look for a fuse but did not see one, but i think there is one for it somewhere, any idea where the fuse is located?

 

good idea, only problem is finding another taco that i can lend to test with, but thanks for idea

 

oh u speak my tongue lol. yes it is the OE taco

 

thanks anyway for the help.

 

just unpluged and reconnected all wires into back of taco, no fix. taco is a VDO, was going to use multi meter to find earth wire but forgot to take it with me to the truck (in holiday mode LOL) so i will make sur i take multi meter with me next time and try and find earth wire and run a new one to earth and see if it fixes it. failing that i will have to get cummins to check it for me, oh the pain! the pain! i really hate paying cummins prices, just feel like i get shafted every time i walk in their door, might have to start taking some KY Gel with me to Cummins

 

GREAT NEWS, GOT TACO WORKING, stupid thing runs off the alternator, and it had blown a fuse!
