Location of Turn Signal Relay in Circuit?

[ricola]

I had a similar issue with my 'wire from scratch'. From memory it was to do with the polarity of the feeds, there was an error in the diagram I was working from.. Might have been something to do with the change to electronic relay?

Thanks Rich, turns out it was an odd effect commonly used in automotive wiring, you have to hook up the (-) of the LED/bulb to the control/output of the signal relay and the (+) to any 12V (+) source. Its not a normal ground, but between pulses of (+) exiting the relay, the same post acts as a (-)ground that will light the dash indicator. The relay is turned on with a load, so what was happining is that just the indicator LED would trigger the highly sensitive LED specific relay to turn on. If you can see both, you'll notice that the turn signals will blink alternating with the dash signal indicator. All good now, just have to sort out a faulty S2000 starter switch...
