got a bit of a strange issue. Basically I decided I didn't like my over complicated dashboard with its awful wiring, so decided to redo it, but with a change. My car originally had line of sight clocks, without a rev counter. I have now decided to go for a centre speedo. I have put both left and right hand indicator wires together for the lamp to illuminate when they are on, but now both left and right hand click very fast, so they don't get time to hardly illuminate. The hazards work correctly, and the green light does illuminate for both left hand and right hand directions. I have tried another relay but unfortunately this didn't work, the only thing i was wondering is whether the lamp holder should earth out on the speedo body, or whether it should be insulated from it, as the alternator and oil pressure lamps are?
Any help is much appreciated, thank you!
