thanks Agro

still Not working
- horn
- washer (this may just be pump)
- heater fan
- reverse lights
- handbrake warning light ( dummy lights work as charge light comes on with ignition)
- temp (this fluctuates between .2V and 9V odd with ignition on. my HJ has 12V constant
- oil warning - does not come on with ignition

i have not earthed starter. I put a larger cable on starter > +ve batt and larger cable for earth to alt > battery

it is electronic ignition (aftermarket bosch)

i just checked the old boys WB 6 banger. There is also no earth at coil with ignition on, not running.

A concern of mine is that there is no earth for instruments at coil as per VB -VH diagrams i've looked at.

It's a HZ 253 in a WB with wb 6cyl auto harness running elec ignition.
