took the cruiser down the coast for the weekend and got a bit of a problem. when i am at very low revs and do anything that consumes electrical power (i.e turn the headlights on or touch the brake and the brake lights come on or put it in reverse and the reversing lights come on) all the warning lights flash intermittantly - the fuel water trap warning light, both the
orange & green turbo lights, the air filter warning light and the alternator lights flash and continue to flash until i increase revs - then they stop flashing until i get down to low revs again - i.e if i decelerate to corner and apply the brake the combination of low revs and the brake lights coming on cause all the warning lights to flash - anybody heard of anything like this before?

Hi Jelm, I also have a HJ61 and have noticed this happen mainly on quick deceleration, situations where I have to get off the throttle to slow down for a lights change or sudden stop, the dash lights flash for a second & then go off again. It has happened intermittantly since owning the vehicle & resulted in a stall once some time ago.
I recently had the turbo overhauled & the problem seemed to go away, I also had the fuel system serviced (pump & injectors) and advised the service agent of this particular quirk.
He seemed to be of the opinion that this is a problem related to wear in the pump and was a result of the idle speed dropping down too low on a sudden lift off of the accelerator, the pump goes to a no fuel situation & the pump is slow to react to achieve an idle. (sounded like that!)
He advised me that the problem was fixable but the pumps on these models are expensive to repair and unless it was a real bother to put up with it. I have noticed that it is idling a little higher now than before but as of yet there has been no repeat of the problem.
I did
shop around and was given the same advice by all the other diesel service agents in the area in regard to cost and the dash light issue.
Hope this helps, I would be interested in any other possible causes/fixes too!

have done some looking into this damoHJ61 and this is the story so far - i didn't think it was related to deceleration 'cos it happened at idling or crawling speed - if i just crawled along in drive it would happen - take it out of drive and it would stop(sometimes) - checked the alternator and brushes and sliprings were fine - but to
check the alternator i undid the air con compressor and cable tied it to the guard - drove around for a day an NO warning lights at low revs - put the air con back and fitted the v-belt and the warning lights came back so it was definately related to the load on the motor at low revs - now i have just had some checks done on the motor - compression in all cylinders between 400 and 480, reset valve clearances, cleaned injectors, checked boost (upto 8psi) so all seemes ok BUT the injector timimg was way out - only 3 degrees BTDC - should be 11 - so reset the injector timing and guess what - NO warning lights - only picked it up this arvo and have only driven 40kms BUT NO warning lights at all - not once - previously they would come on at every idle - every set of lights, or corner, or
stop sign - i'm not going to say it's fixed BUT it is definately better - it hasn't happened yet!!! - i'll drive it for a few days and let you know how it goes.
