Body/Chassis ground upgrade.. do it!

[Jay18]

i have done an upgrade on my body ground to the battery and was suprised at the difference it made, i got rid of the small mostly broken wire that was there and replaced it with battery cable..
it really does make a difference, all of the interior lights were alot brighter and my radio seemed to work better too.
i found that the clutch cable bolts were a good ground point as it was think steel there and a short distance from the battery, so i bolted it to that using the existing bolt.

small rusted wire compared to new battey cable..

just need a new pair of terminals now and im sorted..

Can you show me the new earth point? I've got earthing problems too. I experimented with a spare bit of cable on the headlights and a bigger earth wire made them brighter.

make sure you remove the clutch cable mount and clean the metal and everything and use battery cable works great mate huge difference...

Oh, I see, the mounting thing. Thanks. I shall go find myself some suitable cable.

let me know when youve done it and if its made a difference, it did for me..

An easy way to find bad connections, poor earths, high resistance circuits is a simple. Volt drop test

All you need is a volt meter or multimeter set to volts DC

It's easy because you connect the meter in parallel with the circuit and can test for faults in the +ve & -ve side of the circuit

Connect one lead to B- and the other to chassis ground. You are making a second path or the current to flow, since electricity always follows the path of least resistance there should be 0 reading on the meter as it should all be going down the original earth lead

If you have a voltage reading then the earth is poor because the voltage is finding its way down through your meter instead of the proper earth wire.

Works +ve to +ve as well like checking power to a component.

Always remember that the best earth on the car is the battery -ve post.
