 Re: Earth strap
I've measured a 13A (current) with engine running and all lights and radio on!
So I've just placed a 4mm2 wire in parallel with the yellow one and lowered the load.

 Re: Earth strap
Roger, the engine & gearbox assembly is isolated from the chassis by rubber mounts to limit vibration and noise transmission, however there's a path for current to flow between it and the chassis/body unit via the driveshafts and suspension arms, isn't there? Probably best if that 'stray current' was kept to a minimum, mind you... Roger V wrote: Thanks Jasu Just as i thought. And as you say, it will find away back if it can.

 Re: Earth strap
Thanks Ken (everyone) Earth strap has arrived. Not fitted because have been dealing with the oil leak. I probably won't notice any difference when I do, but I will know it has one. Then there's the charging issue to sort out!

 Re: Earth strap
Earth strap fitted Charge appears to have raised to 14.4v at the battery Voltage indicator on the dash is still in the grey zone! Hmmm

 Re: Earth strap
I'm gonna look for threads on this. Any help or direction is appreciated.

 Re: Earth strap
Roger, 14.4 volts should be fine as the target charging voltage for a lead-acid battery, although any higher than that and the battery will start to 'gas'. As Geert has already advised, I'd trust your multimeter rather than the original dash-mounted voltmeter in the car, which can lose its accuracy with time...
