I have a 94 and need help finding a wiring diagram for this truck . truck isnt charging . i put new batteries and a new alternator on truck . bought it as a cluster mess and need to find out why its not chargin. thanks for any help

 

Buy a FSM, either new through Genos or on Fleabay.

Alternator charging is controlled through the PCM, if everything else is fine, you can look in user Infidels galleries and find a really good illustration of how to put a external regulator on and say the heck with the PCM.

 

Take a look @ post # 19 it might be what you need.

Strange, it just worked fine for me.

 

Infidel, thanks for posting that link. It has some good info. I have been looking for info on a Toyota Echo. Not even a Haynes Manual is available. I found the info on this link.

Thanks again. ET
