Handbrake warning LED and MIL LED not working

[Rufus Roughcut]

As in the Title, during diagnostics I found that D7 on the circuit board is missing



I tried tracing the components on the circuit board and it would appear that I need it ?

Does anyone have their instrument panel in bits and could check for me


Also the MIL light does not come on when the ignition button is pressed (Engine not started), if I pull off one of the throttle pot plugs it doesn't come on.
Does the MIL light only come on when there is a fault and the engine is running ?

Thanks

Mark

Hi, I had the same problem as you when i bought my 97 Cerb,
Raceproved fixed it for about £46, very reasonable i thought since im not very good with electrics,

Might be worth giving them a call, there always very helpful

Hi Mark,

IIRC I didn't have a D7 on mine but the handbrake light still works, I'll check this evening. Firstly I'd check the switch on the handbrake mechanism under the leather surround in case its got stuck.

Also my MIL light wasn't working at all. I traced it to it being a little fuse on the board, you can see it just on the right hand side of your photo, might be worth putting a meter across it. When I got it working, it was annoying having it buzz away all the time when the ignition was on, so I cut the leg of the diode which fires the buzzer and now the MIL just comes on but without the buzzer sounding. Buzzer still works for everything else.

Rich.

Thanks for the reply Gray

Rich, you were spot on

I didn't have a circuit board type of fuse so temporarily soldered a 20mm 0.5A on flying leads, guess what? it cured both faults

I've ordered the proper ones off of ebay, only cost a quid for 5..

Thanks again

Mark
