1hdt alternator help (1 Viewer)

[Dusten]

So for the longest time I've had issues with the dash lights blinking while driving

I suspect it's the alt and not the plug simply based on mileage

I'd read that a tercel alternator fits. But when I bought one, mines different.

Mine was slightly larger and had an oval plug. From reading some older threads this seems to be a slightly newer alternator.

I'll grab the part number off it in the am, but I'm pretty sure it's a 110 amp. Which means the 1fz alternator won't fit.
I'm trying to line up exactly what will fit.
Radd cruisers sells one and mentions it's larger than the early 80 alternator so I'm trying to see if it's correct for me.


Fwiw mines a 91

I believe I have the 27060-17040 but with an oval plug

There are adapters available to adapt between the old and new plugs, or source connectors and make your own.

One example

Alternator Connector Adapter Plug for Toyota Hilux Landcruiser Hiace & Denso | eBay

This adapter/connector is for the 3 pin Nippon Denso alternators. The adapter is used for converting a round plug to the oval plug type. It can also be used to replace existing oval connectors. These connectors are common to fail and cause a bad connection damaging the alternator regulator. We...

I didn't want the adapter because I wanted to repin my old one with new plastic.

I found the connector elsewhere today after some more digging. I knew I should've dug more before I posted. Always happens.

Sequoia 150 amp bolts in, just swap the drive pulley. Failing that the HDJ 100 bolts in, two options, 100 and 120 amps, straight bolt in with three pin oval connector.

Everything I read says you need a bracket

I've tried and the Sequoia alternator does not bolt in - tried both factory brackets too.

If we are talking 1HD-T then I am afraid you are wrong my friend, apart from the body Sequoia being a little wider meaning a minor modification with the adjuster bracket, the length of the mounting lugs on the alternator are identical.

Not wanting to sound like an arsehole, but one member says he tried two brackets, you read you need a bracket, if we are talking 1 HD-T then only the OE adjuster bracket needs a slight modification, and of course the Sequoia has a serpentine style belt and pulley, the double pulley fits in place of the serpentine one, one nut and done.

In my build thread going back quite a number of years, all the information is there, unfortunately I cannot stay on the internet or even watch TV for too long otherwise I would track it for you.

Dave.

I'm talking 1HD-T. I've tried it, first a few years ago and again more recently. Using a Sequoia 150A alternator - the distance between the mounting bolts wasn't the same, holes for adjuster bracket didn't line up, and the alternator would foul on the adjuster bracket when trying to swing.

I should say I don't think it would be all that hard to make a bracket that works, but I couldn't see a way to simply modify my existing bracket. Other than cutting off and re-welding the arched portion.

Everything in was reading said it needed a custom bracket. But that may have been for gas trucks.

Dave, my point is I couldn't find anything regarding the bracket. All the old pictures were s*** or gone. I'll dig through your thread. Modifying and fabrication is not something I'm afraid of.

Well unless the Sequoia has different alternators (apart from the amperage) then our findings are clearly different. Yes the adjuster bracket is dismantled and a part of it is not used. The actual mounting bracket initially gives the impression that the Sequoia unit does not fit, but there is a spacer in the bracket that allows for manufacturing tolerances, that will move if a nut and bolt is used to slide it right back.

Last week I had to fit the 120 amp version when the repaired Sequoia version failed, I had rin with a stock 80 amp for some time because the Sequoia is not sold in Spain, so spares are like hens teeth.

If you can spare the time to look through my long running thread, you will not only find the details, but also how it was fitted with pictures. If I can find the receipt I will post it up, it will have a date, so tracking down the fitment date in my thread will be easier.

Dave.

I'll dig through tonight at work

I swapped in a 1991 Tercel alternator 80A a while ago then I went with M2k.inc for an upgraded alternator
when switching to the 1991 alternator the regulator is different and you have to swap your old pulley over.

hdj81 Please confirm DASHLight sequence...

Normally when I Start my cruiser I would wait for the Glow plug light while the key is in the ON position to turn off before Starting. Today I noticed I am not getting a glow plug light... When the key is in the ON position I don't have any lights When the key is in the Start (cranking the...

HD 1HDT alternator options in US

Looking for high output alternator options readily available in the US market. I’ve heard about going to the Tundra/sequoia 140amp, but can’t seem to find the brackets needed anymore. I’m going to be removing my 24v starter also soon and going to a common parallel dual battery setup. Thank you...

I have a 100 amp. The tercel is a smaller body. It doesn't fit.

While chasing reasons for my issue I noted voltage at idle was good. While revving was good. I turned on all my lights, fridge, seat heaters, ac, basically anything that draws power and still had 13.7v at idle.

I then found that the main negative cable at the battery was loose. Not even a little tight.

Removed it. Cleaned for good measure and replaced the hardware before re-installing. Everything seems good now.
