Re: Wiring harness



All.

Thank you all for your calming words, and things to try. Replacing 
the harness is now on hold since I have been convinced this may be 
overkill!

My current list of woes runs like this....
* LHS door lights don't work unless the key is fully in the ignition

** Ignition P1
Temp gauge records electrical system use as a running total. Put 
indicators on and the gauge 'bumps' upto to max. Use the lights and 
the higher the beam the faster the gauge moves. Eventually reaching 
the 'P' of 'temp'. Gauge does not zero by itself, but is 'reset' by 
turning to P2

**Ignition P2
Pre-start the oil pressure gauge oscillates ~30degrees when 
indicators/hazard lights are in use.

**Once started the temp gauge still moves through ~30degrees with 
electrical load. Switching on main beam/air con shows a false sudden 
engine overheat condition. The gauge then drops slowly to 'normal' 
when the function is turned off.

In all modes, the red warning lamps (handbrake etc) on binnacle 
and 'lock door' on centre console dim/flash with indicator use.
No more than one function can be used at a time without knocking out 
the indicators. i.e. with fans/lights I get no indicators.
Lights appear dimmed in all modes.

Fuel gauge reads low except when in P2 pre-start.


So far I have replaced the battery, fuses and installed a full relay 
replacement kit. The voltages measured at jump posts are within the 
manuals recommended figures. Continuity between the front ground 
point behind LHS wheel *appears* good (I'll recheck). Running an 
additional ground cable from that point to the enigne ground point 
doesn't make a difference.

I was particularly interested in the post that suggested a screw may 
have gone through a cable, it's something else to consider!

I will be removing the binnacle on Thursday/Friday, in the meantime 
any and all further suggestions are gratefully received.

The LED pictures have helped, I should have looked there first, doh!
