Have a set of these in my R300. Been working fine, however the shift down light (far left green light) only shows when driving. All the lights come on properly when I switch the ignition on.
Anyone have an idea, or had a similar issue?

Thanks

Mike

Mike, you could have a read through this thread - sounds like similar symptoms, but different cause maybe?
Worth a try, though...

Either that, or have a read through of the downloadable instruction manual to re-set the unit - http://www.aceserve.co.uk/

Do you mean the shift down light stays on all the time, regardless of revs?

If you have the re-programmable shift lights then check what the shift down value is set to. If that seems reasonable then I'd expect you have a short somewhere. There's two places I would expect to find a short, the first is inside the LED unit, the other is inside the 7 pin plug that connects into the control unit.

If all that checks out then you'll probably need to contact ACES. They're very helpful and will sort you out

Mike - The green light is there because you're not giving it enough beans !!!!
Get it into the power band (over 4k) and it goes out.

It's very bright at night.....

Also check that you have the number of cylinders set correctly on the unit.
