I've had lighting problems with my 70 flatbed dump since I got it. I know I can fix it but this one problem is vexing:
The left turnsignal blinks real slow, sometimes not flashing at all. when it doesn't flash the indicator light stays lit and both front and rear signals are on bright. The right turnsignal works fine and all flash as they should when the 4-ways are on.
Any ideas? Is it a grounding problem?
thanks, abe

Re: slow blinker
I doubt a grounding problem if all lights work normally on 4-way flash. You may try the easiest fix first and replace the flasher with an upgraded unit that is variable load. These do not depend on the load of the bulb to flash.
