Hello,
I am new to ih8mud and what an amazing place to share our love for cruisers.
I own an HJ60, which I am now 'fixing/upgrading' and live in Africa.
First of all I would like to thank all the people that participate and help one another. I've been reading many of the threads as I recently started working on my truck but never posted anything and found them very helpful and also a great atmosphere.
Today I've encountered a sort of road block and hopefully someone can help.
I have searched the threads but couldn't find the info I'm looking for.
Basically this is my situation:
I've recently added a 12V (original is all 24V) circuit to my cruiser to power various accessories (dash cam, tyre pressure monitor, stereo, and others). Did this via an additional fuse box and main line from the 2nd battery -ve post. Grounded the fuse box to the body via a bolt in the cabin. For some devices I used a relay as I want them to power on as ACC.
All works well apparently.
I also went trough the original harness in the engine bay and cleaned it up a bit but didn't make any changes. I have howeverd moved around the harness, tied it up with tape where needed etc.
Yesterday I went for a test drive and noticed charge light was coming on when revving up the engine, even just above 2,000 rpm.
Then noticed the voltage meter in the instrument panel going over the limit (32V).
As this clearly means overcharging went straight back home. Checked the regulator which seems to be ok (followed the tests indicated in the workshop manual).
I did find the regulator ground wire to be burnt out and interrupted. Looks like it shorted but seems from an old event. Probably when I cleaned up the harness it broke alltogether.
I repaired this wire hoping it would fix it but I imagined it wouldn't, since the regulator is also grounded via the body anyways.
I did a test with the regulator cap open and engine running. By naked eye it seems the regulator relay remains in one position, and I assume this is telling the alternator to continously charge.
I haven't checked the fuses as everything works but I will do tomorrow. If main engine or charge fuse were blowin I assume the cruiser wouldn't even start.
To cut it short, can anyone help me understand what's happening?
I haven't tried adjusting the regulator and was thinking of doing that next, but perhaps someone has seen this before?
My brother has an HJ62 which occasionally behaves the same way but in his case it's random and seems like regulator relay gets stuck but then starts working again. Mine has been working flawlessly for years and this has suddenly popped up and it's doing it constantly.
Any help is greatly appreciated.
