LED Indicator resistors

16 ohm and 10 watt

wire them in parallel, ie where your connectors are, bridge across = no problems

with my early falco i only needed two on the rears indicators - none on the front, with the standard flasher unit

if i did not have the "fucking fat bitch from hell" manager I would have not been at work today and would have done the picture - any one looking to recruit a senior nurse? am going to tell them to fuck off on monday, and exercise my right to leave immediatly - is small minded, petty etc, but i really do want to leave the fat whingebag in the shit

Just not an elegant solution fudging the LEDs to simulate the current draw of bulbs in order to make the relay work properly. Don't like relays that set time intervals by how long it takes for a bi-metallic strip to heat up, bend and make a contact - an electronic timer circuit is much nicer. Also you're not throwing away electrical power as heat in the resistors. Yeah - overall it's not a big deal but just goes against the grain.

just a thought ? if i fit four led indicators ,,,is there a relay that will just slot in to compisate ,, iv read alot abot these led surly its not that simple

Brilliant thanks Aladinsane - off to Maplins today then.

Joe - I bought what was advertised as a straight swop relay switch and it didn't work.

Job done - thanks Aladinsane. Just need to tidy up the wires with some heat shrink. Interestingly I had to use the replacement relay though. They wouldn't work with the original.

Unfortunately it's not that simple Joe. Because the indicator circuits are linked through the dash teltale the extra current racing about the wires not used by the LED's jumps through the teltale and lights up the indicators on the other side.

My earlier post in this thread has a link to a fix for this on the AF1 site, which comprises a couple of diodes at the teltale that act as gates to block this.
