*I did some "research" today, and found the following:
All bulbs are correct.
I new that the RH rear lightunit had a bad ground.
So when I had all the rear lightunits open (disassembled) and had marker lights on (small bulbs front and rear) the RH Rear blinker wire touched the groundplate and so started the RHrear marker light to burn (with no official ground connection attached).
*you must know that in regular use sometimes the RH blinker started to blink faster and slower, like a intermittent fault in that circuit? (all bulbs are OK)
*with the ignition circuit off, all wires connected correct (the RH rear Ground correct also) and pulling the warning switch, all four the blinkers should blink, but not so the RHRear.
* When the Ignition is on, there are periodes that the RHRear blinker light does not blink at all, a sort of intermittent period in intermittent etc.etc.
(I hope you still following me, since I find this complicated to explain)
* I think there is some gremlin in the RH blinker circuit.
has any of you any Idea what that could be?
