Hey all, happy new year.

Had a search on a few sites but just looking to hit the nail on the head with this - got a 84 hj60 (2h manual), looking at an imported 12ht 24v to drop in but was just looking to see if someone's done it and if there were any dramas? Alternatively those with an import hj61 are there issues with getting 24v parts in oz, do most car fridges run on 24 as well as 12? Other accessories like cig lighter charges etc? I'll be looking at popping an inverter in the back and i've seen 24 to 240 ones but just wondering about the day to day practicalities of 24v in oz? Not too good with this fancy electricity thing so sorry if they're dumb questions...

Cheers,

Pat

It would be better to change the 24v bits on the 12HT to 12v. Swapping the vehicle to 24v would be a bigger job and the 12v bits required would be available locally as all crusiers with 12HT engines sold new in Oz had 12v electrics.
I wouldn't be surprised if the bits that need changing like starter, alternator, EDIC motor, temp and oil pressure sensors etc would swap straight over from the 2H to the 12HT.

Fair call, that's what i've been leaning towards given old mavis already has everything in 12v. So am I right in thinking that really there are very few parts that I would need given the differences between 2h/12ht (won't need new glow plugs etc), if I can use the existing 2h parts (starter, alternator, aircon, heater etc)? Then my current dual batts will just stay hooked up with the isolator rather than in parrallel for 24v?

You would have to check re the glowplugs, I suspect they may be different.
The rest of the 12v system will stay basically the same.
Once you've got both engines sitting side by side then you can try things like the starter, alternator etc. The 12HT alternator will likely have a higher output than the 2H one as most 12ht's inOz were fitted to Sahara's with all the elctric doodads so needed a higher output alternator. But if your 2H one is supplying enough power for the truck now then the 12ht will not need any additional power.
While the 2h and 12ht are basically the same engine family there are differences internally so you will have to check that bits from one to the other will fit.

Just remembered that I don't think the 12ht has glowplugs as they were direct injection I think. Could be wrong was a long while ago ;-))

Thanks peter, yeah the 12ht is direct injection so no glow plugs. I was thinling of having them both side by side and piecing it all together as well so good to hear you've got that idea too. Good point on the alternater power, given she's a poverty pack cruiser with no electrics hopefully the current one will work fine. Otherwise if it struggles I can jist source a 12ht alternater.

Cheers,

Pat

Like Peter, I don't think 12HT had glow plugs. Definitely direct injection.

Also thinking the oil pressure switch might need to come off the 2H. Found them @ $48 on eBay.

Also found plenty of 12v alternators there, though got side tracked and didn't find any for 2H/12HT, with the vacuum pump driveshaft.
