I have a 1984 Toyota Odyssey motorhome with the 22R. The starting battery is not charging. Battery is good. Alternator was bad. Replaced and still no charge. Had new alternator tested and it was bad too. They replaced with a new one and tested before installing. Once again, no charge coming from alternator. Not sure if this one is now bad too. There is a simple three post battery isolator that seems to be working fine. I even bypassed it with no luck. What else can it be?

 

check the fuse box under the hood, there is a fuse for the charging circuit.

 

Hey guys. I have an 88 p/u 22re.
Charge lights ARE on in Dash. I replaced alternator (and battery because I'm 80 miles out of town). They told me old alternator was good. I replaced anyway I can't take chances. Lights are still on and I've checked fuse under the hood and all under dash fuses look good. Any ideas on tracking this down? I was thinking maybe I have a bad ground somewhere? Ahh maybe I'll replace the fuse under hood to be sure...
