Hi, bit of a basic question but...

I get the concept of the chassis and engine/gearbox making a common ground but I wanted to check is it best to have the negative from the battery connect to the chassis and then a further cable from the chassis to the gearbox to be certain of a good earth?

Thanks,

Neil

With a fibreglass shell you can't have enough earth connections. A metal body normally routes the earth to lights etc.

I have put earth blocks near every set of electrics, 2 by engine, 2 under dash and 2 more under bonnet. These connect to the nearest chassis point and all lights etc have individual cables to the blocks

I used marine quality from a ship's chandlers

It`s a yes from me and go a step further... Chassis ground to gearbox and VW did it for decades and then a ground cable from gearbox to engine itself. A good, fully charged, battery should give a voltage reading of a tad over 13volts.  ;-)up ;-)up

tried a different approach on the kango battery earth to gearbox and 2 insulated buzzbars for the rest back to the battery neg so in theory the current does not flow through the pan accelerating corrosion when used over winter with salt around. The pan will still be negative as mounted electrical items are not dual pole insulated and the clutch, choke and throttle cables will earth to pan.
