Thanks for the link! :cheers:

I have a 1988, went through the changing bulbs, finally just sent the unit out to be re-furbished, save yourself some grief and just do it!

did the same on my '84 sent it out and had them go over it cost about $200 should have told them to look for a ground problem as this is what kept draining the battery if i didn't drive it every three or four days sent it back for the ground/battery drain problem another $200 all is good now
