1HZ Glow plug Timer

Hi Nick

I had a HJ60 diesel. Used to blow glowplugs often as they were I think from memory a 6 volt plug.
It turned out that the circuit board that controlled the plugs (situated at your feet) I think it was passenger side but a long time ago.
As I was saying this circuit board was shot and a new one was $800 odd

I replaced the glow plugs with 12 volt plugs and fitted a push button on the dash. I utilised the existing relay.

I never had to replace another glow plug. I used to hold the button in and count to 10

I lived at Kingaroy and it got pretty cold in the winters.

Hope this is of some help

Gday Nick,,,,Did you check the glow plugs while still in the engine? I have had at times checked the plugs with a multi meter and they checked ok but some were in fact burnt out when checked individualy accross a battery. I think the timer works off the resistance from the glow plugs and if one or two are burnt out it gets a false reading and shuts off early. If you check the plugs accross a battery be carefull as they are very low voltage and you only need a touch for them to glow or you will burn them out. Regards Nav.

Nick,
I have an 80series with 1HZ and have the same problem. However mine only takes a bit longer to crank 1st thing in the mornings or when its winter. I usually glow them twice by turning ignition off and back on again before cranking and it alwasys starts 1st hit of the key....
I havent bothered to check mine as i thought this was normal, so ill be interested to hear if you find a fix for this....!
Cheers
NUTS!

G'day Nick,
How's your battery??..
About a year ago, my Patrol (TD42T) was displaying the symptoms you describe, & I "chased my tail" for a while checking glow-plugs etc., before I worked out that the battery had dropped a cell... might be worth checking (w/- a load tester)...
