or should I do a lead fron neg terminal to chassis ?..then a lead to transfer case connection ?

got to do both points of connection ?..just don't understand ..the order

Could you just replicate what you have with 2 cables with eyelets on the ends?

Just joining them at the point the original cable had the middle eyelet at?

You've lost me now ???.no idea what that means


I have a negative battery terminal ??and two points of connection ??.chassis and transfer case ???.how do I connect with one or two leads ?

Ok on further though I think I got it

cable from neg terminal to chassis ?'then another cable from chassis to transfer case connection ?
.
that should do it ???right ?.

To expand the above, some of your electrical circuits are 'earthed' to the engine/gearbox/transfer case and some to the chassis, but both have to go to the battery negative. Some cars have the battery to the engine and some to the chassis, with a separate connection between the engine and chassis - somewhere.

Connecting both to the battery is necessary as the engine is on rubber mounts and hence not very well connected to the chassis. Having a branched cable is actually rather unusual.

failure of the connection between the engine and the chassis can result in some surprising effects such as I remember on one occasion (actually in a Series 2a) when the starter was playing up, and when you operated the starter, the speedo lit up.

Correct
