help.double trouble

[braceuself]

car gettin on my t*ts now.rev counter only comes on with the lights and charge varies between 12v and 8v.so i end up with a flat battery.not sure if both faults are connected.anyone have an idea?

Sounds like a bad earth m8. Could be relying on an alternative earth path when something else gets used. Maybe the RC is using the clock illumination earth for a return path.
Check all your earths. A new one on me that is.

You say double trouble, is that why you posted it twice? ;D ;D ;D

[braceuself]

yes lol

Believe it or not a faulty/shorting wiper motor park-switch can cause your rev counter to fail.

The park-switch (wipers) runs on the same circuit and it can also cause the main fuse to blow or the wiring to melt if your really unlucky.

So if your wipers don't park themselves any more, then chances are it's the park-switch that is to blame here.

Also make sure your fuse and in-line fuses are all wired in correctly: -

wipers are fine.i'll check wires when i get home.prob a fuse box problem.ooh i now remember why i sold my last mini 10 yrs ago:-)

[taffy1967]

Why, because of a dodgy fuse box?

Mine is 18 years old and I'm not having any problems as I replaced my fuse box last Winter and boy did that make a difference.

The rear contacts on the main fuse box gets very rusty with age, so when fitting the new replacement, give it a coating of Vaseline first so it doesn't rust out any time soon.

Don't use Copper Grease though, as that may create a short.

There, now would you have this level of support with a different car? Plus a new fuse box costs around 20 quid that's all. Hardly breaking the bank now is it?

[taffy1967]

Just make sure you wire it correctly: -

4 Fuse box wiring colours: -

White - Green
Brown - Purple
Light Green/White - Light Green/Orange
Red - Red/Green

[taffy1967]

Oh and unless it's an injection model, the rev counter wire is black/white (I believe?) on the coil.

So check that's connected properly too.

its a green wire going into fuse box but it is black and white going to coil.the aa man put the rc wire to the fuse for the lights! Problem solved :-)
