HJ gauges not working

Hi all,

Recently the gauges in my HJ all stopped working (Fuel, Temp & Oil pressure).

They were all working, although not with any great accuracy, but suddenly stopped. Speedo and all the warning lights seem to work fine.

I have read here about the voltage regulators causing this type of thing on HZ, could this be the cause on a HJ and if so, how can I fix it ?

Thanks in advance.

Which Alternator HT v8?

took my alternator in to the auto electricians to replace. Apparently they don't just bolt in anymore. Mine is an old style with the pronged plastic pin at the top with an external regulator and will need some wiring done because the new ones only have an internal regulator. I don't know electric stuff but just wanted to know is the the best way these days? Apparently better and more reliable. They don't rebuild them anymore apparently

starter motor dramas continuance ... grrr

So I thought I had it sorted, car was starting first click every click for the last few weeks, then .... Fkn tick tick tick.. Bloody thing started acting up yesterday.
What I noticed was that the brand new relay (30amp fused 4 pronged relay) i put in to replace the old I figured was faulty, was getting warm to the touch even when the car was not running, ignition off. So I disconnected it and the car starts first click again.
My question is that it has always had a relay there its factory loom leading to it, but what the hell does it do?

Alternator light stays on

Sorry if this has been asked before, but I can't find a related thread. I have a WB ute with 173 transplanted from a VH commodore. Since I've had it, the alternator comes on after about 5 minutes of driving, regardless of revs up till then.
So, I purchased a new 70 amp alternator from Repco and swapped it out.
Same problem. Lights still comes on.
I wondered whether there is a separate relay/regulator or something that also needs replacing; OR, if it might be something to do with the Immobiliser that it has fitted.

Holden EH Nasco / VDO clock gauge

Hi All,
I have an issue wiring the EH Nasco Clock into my EH and was hoping for some help and or advice. I have a copy of the Nasco instructions, thanks to another member. The instructions say to remove the Lamp Globes from the harness, which means I will have a pink wire and a coloured wire for each instrument.
I then connect the coloured wires to the instruments..but what do I do with the pink wires?

Grey 138 electronic ignition

Is there a suitable electronic ignition system for a grey motor? I have a one in three miss on number two cylinder. Rebuilt the bloody distributor which was great for 150 miles. Worse when cold. I checked this with an induction timing light. Changed leads and plug. No difference.
