Circuit diagram checking...any experts ? By rob63 (Read 1,114 times)

Just putting the finishing touches to my Adly project, everything is working except the indicators.
Haven`t delved into it too much as weather has been rubbish, but thought I`d post up the circuit diagram I made to see if any experts could check the indicator circuit to make sure I haven`t made a cock up somewhere.
I`m using a battery eliminator so nothing works until the engine is running. The flasher unit has a black wire feed from the ignition, this must have feed to it as the horn is on the same wire and that works as does the tail light. The grey wire from the flasher unit goes to the indicator switch, which then feeds the indicator wires though the switch.
There is no clicking from the flasher unit but I did try a multimeter on the blue feed wire on the right indicator but only got about 8-10 volts.
Any thoughts would be appreciated

I'm not sure how a battery eliminator works but if it's all AC in your system now that may be the problem. If you have a DC flasher relay it won't work with AC. Rich

The battery eliminator sits in place of the battery, wires in the same, effectively it`s a capacitor which stores a small amount of charge. It`s fed by the red wire from the reg/rec which would normally feed the battery, so would the voltage still be DC ?
The flasher relay should be DC I think, as it used to work off the battery without the engine running.

I would say yes it is dc , I would explore a poor ground .

Cheers bud, I`ll investigate further

Yeah that would be DC if it works with just the key on. How about a bad flasher relay? They're a pence a dozen so maybe just swap it out and see what happens.....right then! Rich

Yep I think the flasher relay will be the next port of call if the earth seems ok

[rob63]

It looks like I`ve got a bad flasher unit, checked earths and ran a different power lead to the indicators and they come on, so basic circuitry seems ok.

Popped a flasher unit on and it`s all working. Also had to rewire the tail light to the headlight circuit (yellow wire from stator) as the voltage wasn`t enough for the indicators and tail light at low revs. Had a test ride around the block and it all feels fine. Now for the MOT test.

does mot mean man on top?

Nope, Ministry of Transport
