Earth problems

[STE VR]

Might be a daft question but I have got problems with my stereo reception which is now quite poor when it was actually very good. I've also got problems with my brake fluid resevoir switch, it's now always on even tho the switch/fluid is fine (handbrake switch is ok). I have tested the earth side of the wiring to the switch at 46ohms which is the problem. Can anyone tell me if these might be connected to the same earth point and if so where??? I just don't want to check every earth point if i can avoid it at the moment. Mine is a 95 4.0litre serp if thats any help.

Not sure if thats clear......?

Many thanks

Steve

If you think it's an earth problem why don't you just attach the earth side to any other earth nearby and see if the fault goes away. If it works then job done, it won't hurt to leave your "new" earth wire permanently attached.
Does your brake warning light go off if you disconnect the reservoir?
Just a thought.
Cheers.

Hi Paul, i can't really leave an earth attached as the wiring comes through the wing about 1 inch and can't run another wire so it's probably easier to correct the earth fault as it also affects the radio. if i disconnect the resevoir switch i'm under the assumption it goes 'fail safe' anyway and leaves the light on. I think it needs the circuit made to extinguish the warning light(might be wrong tho).

Thanks for the thoughts

Cheers

Obviously there is a bulb somewhere in that circuit. I don't know whether it's on the positive or negative side of the switch, but are you sure you aren't just measuring the resistance of the bulb?

According to the schematic in the bible it just shows the fluid switch switching to earth. I don't know if it goes through/switches a relay as its part of the handbrake circuit too. One wire has infinite resistance which i assume is the return wire(to where i'm not sure, possibly relay or bulb) and the other wire should be dead to earth i think. If i was measuring the bulb resistance would'nt i have to be on the live side too??

ps..not sure if this makes any sense as i've been on the since 12!!!!
