The lights in the grill of my 71 Grabber have become intermittant lately. Sometimes they work and then another time I drive the car-nothing. Are they powered by a relay? Any sugestions other hunting for a loose wire and bad grounds? On another note, The muffler became disconected (read "broke off") from the pipe and was removed. It actually sounds decent with just the stock resonator behind the original 302! A little flatulent, but way better than the local kids in Hondas. I am just collecting parts and trying to find the time to swap in the roller engine, so a fix on the stock exhaust is not really in the cards.
There is a relay mounted in the drivers side kickpanel. This is assuming it is an original Grabber with the switch mounted under the dash. If it was just an add on by someone, who knows what they did?
