Alt light stays on in dash

make sure the wire that has the arrow to it is grounded well and make sure there is a body ground form abattery as well as engine. Check the circuit breaker running off the starter relay from the black wire, it may be attached to relay with just one wire running from it. then check the back of the ignition switch to see if the harness is burnt up there. I may still have a repair harness that was used for these but not sure if it's right or not if you need it. see pic

Thanks Hmac...
I pic was so small I could not read it.

click on it it should enlarge that is about all we can send through this site

Also to let you know I did replace the ignition switch with all the other parts....forgot to add it to the list...

Now when I click on the pic It takes me to a blank screen...can you email me the pic.

Thanks sooo much....

Also to let you know..we put a voltage meter on the Battery while running it and get 14.8...

it's charging then thats' not to high if battery is low also there may be insulators that go on the voltage regulator if the holes look bigger than the bolts then there should be. the VR would look like it has half to 3/4 holes where it goes. This is a test for my memory cause I haven't worked on one of these in eons. check to see if the insulators are on old VR if you stil lhave it.

We did bolt on the old VR and the light stayed on..but maybe the old one was bad..The new VR look actually like the old one

Hmmm..maybe the new model of VR need to be insulated like you say...

then there should be isolators where it bolts on they will have rubber grommets with metal sleeves or should , if not you are going to have to isolate it somehow so it will work.

Is there a way to test if the VR is working?

if you are getting 14.8 volts to the battery it's working. ford amp gauges were there to look pretty they never really worked that well. tha tis what the circuit breaker goes to.if you have a alight instead of gauge then you wont have the circuit breaker.
