Hi Everyone. I know superglow has been done to death and I have searched my heart out but I cant seam to find a good answer to my issues. There seam to be some knowledgable heads here and I am chasing some detailed info on superglow, especially the glow controller.
Loooooong story short but I have a HJ60 with a 2H running superglow. Its an Australian original 12v truck. And before anyone suggests it yes I know about the wilson switch idea but I really dont want to go down that route just yet.
I have recently done a complete rebuild of the engine after the PO damaged a piston and sold it on to me in bits. I replaced all the glow plugs, the bus bars and the sensor bracket when I did the rebuild. Its also got brand new batteries, a rebuilt alternator and I had all the engine earths re-done. The glow system has been working completely fine over the last few weeks of having the truck back running and its starts and purrs like a kitten.
However last weekend when I was returning from a 2hr drive I noticed a faint burning smell from the engine. I stopped and checked everything but nothing was obvious. I only had a few mins to get home so I carried on. At home I check everything again and still found nothing obvious. A few hours later I went to move the truck in my drive and noticed that when I went to start it the glow light did not come on. The truck started fine but straight away I heard a loud repetitive clicking sound. I popped the hood with it running and found the noise was coming from the Glow Relay. I felt the relay and it was definitely clicking like crazy. I turned it off and have been trying to find the issue ever since.
One other thing to add to the mix is that at the same time I noticed my charging volts were low on the dash gauge. I put a multi meter on the batts and it was only pumping out 12-12.6v at best, so not really charging at all. After getting the alt re checked we have worked out the voltage reg was buggered, which im waiting on a replacement for now.
A couple of other attempts to start the truck have given varied results, most times the glow system seams to work fine. But once its idling the relay will start sporadically clicking again, especially worse when you give it a rev.
My initial thought was the relay was toast but ive had that tested and its fine. I have done some diagnostics and found that the glow system seams to be working as it should, im getting 7-8v-ish on the plugs for the initial glow, then the relay clicks off and the after glow happens. As above once its idled for a few mins the relay starts clicking.
I figured it must be the glow plug timer. Which I have been attempting to find a replacement for. Which is where my headaches begin. Mine is a H12V and I cannot for the life of me find a replacement controller, they are rare as hens teeth and the ones I do find are all 24v. I managed to find what I was told was the right controller from a wrecker but when it arrived it was stamped as a B12V. After a bit of research I found this is off a BJ45 running a 3B motor. (Told you id make a link).
So after that novel here are my questions.
Would the sporadic relay clicking be caused by the controller being toast or could it be something else?
Do you think the controller of the 3B motor would work? Its the same plug but I am apprehensive to try as I dont want to **** any of the system....
As I said I really dont want to go to a wilson switch as I am trying to keep the truck as stock as possible.
Thanks in advance for any and all help!
Cheers.
