voltage

Hey everyone! My 1976 FJ40 has been dead reliable apart from the oil pressure, fuel, and temperature gauges not working. I’m guessing it may be due to the absolutely gnarly aftermarket voltage regulator that’s seen better days. I ordered an OEM replacement from @ToyotaMatt earlier this year and...

2009 LX570 with 169k miles. 20-40A of aftermarket loads on occasion. Swapped out this failing alternator that showed symptoms of low voltage and not sufficiently charging the starting battery. https://forum.ih8mud.com/threads/rth-alternator-suspect-voltage-output.1316746/ Tore this down...

There are two post on the alternator the white is positive. The other is negative correct? Can i connect the black negative wire anywhere I can get ground (negative) or directly to battery negative. Are these the only two wire connected to these two post? Is there another wire? As you can see I...

I'm using Coolerman's adaptor harness for installing an internally regulated alternator from a later vehicle into my '77. I had the alternator checked at the local Orileys to make sure it was charging. I've triple-checked the tie-in of the adaptor harness to the factory harness. per...

Started my rig, 93 HDJ81 and majority of my warning lights came on. Everything sounded OK, at idle, and up to 2000rpm while in park. Fluids check ok. My voltage is reading a bit low on digital dash gauge I have, reading 11 volts and didn't fluctuate up when I revved the engine up to 2000 rpm...

Hi I have a 1999 Land Cruiser with 298k miles. Over a year ago the alternator failed and I replaced it along with a new red top battery. It also has a much bigger alternator now too, 270 amps instead of the typically 100. At nights with my headlights on my voltage will drop a little bit and the...

Mudders, Truck is an 11/1974 F1.5 retrofitted with a 2F alternator bracket with internally regulated FJ60 alternator and coolerman's wiring. External regulator is deleted. I have recently installed a sniper and noticed the voltage seemed a bit low driving around. Around 12.2 to 12.5. When I get...

Ive got a weird charging problem, I thought was the alternator, but i took it to autozone- and it tested good. apparently I have a code for an open EGR, so they tried to sell me a new egr LMAO i dont think thats it) the battery checked out good too... So looking for some advice. Started...

Howdy folks! I recently acquired a beautiful '01 LX470 and I upgraded some of the stock electrical with a 370 Amp Alternator from DC Power Engineering, as well as replacing doing the big 3 (battery to ALT, ALT to ground, battery to ground) with thick 0/2 gauge wire. I added an AGM battery (and...

In case this helps anyone in the future. Before I purchased my 1 owner 2001 LX, the service records state they replaced the alternator with a Factory refurbished alternator about 20,000 miles ago. I don’t know what their problem was. As soon as I purchased my 2001 LX, I replaced that...

Has anyone added a diode to the voltage sensing wire to boost the alternator's output to around 14.6? I cannot find any documentation on the web about this being done for either the 1st gen Tundra or Sequoia. Thanks for your time.

I recently sold my fj60 and purchased a project 1991 fj80. It ran and drove but it had a hard time starting and its exhaust had a rich fuel mixture. It seemed like it had a hard time accelerating but I am unfamiliar with the 80. After its first 20 mile drive it wouldn't start again. I took a...

Hey all, Had been having voltage issues for awhile now, battery wasn't charging, misfiring, plugs fowled etc etc. Anyway, I have replaced the alternator and voltage regulator (which I discovered melted down). Can anyone tell me what type of voltage numbers should I be seeing coming off of the...

Does anyone know what these may be? I want to build a new harness with some maxi fuses for ease of repair

A quickie question for the pros- installing a 12v headunit into my 24v system will require two voltage reducers-- one for full time power and one for ignition power, correct? While searching I also came across the mention that the head unit would not maintain its internal memory if using a...

Hi, all: Long-time reader but have never really posted before. I have really appreciated the wealth of knowledge that everyone has here, and their willingness to share and help out. I have been waiting to post to introduce my rig but, honestly, there's nothing really extraordinary about my...

I have q 71 FJ40 with the F engine it does have a painless wiring harness and Dolphin gauges. I was on my why home from a trip out west from St louis after driving straight through from Brice Canyon NP I made it to KC during rush hour. It was getting light out so I turned off my headlights my...

If anyone has any electrical experience on these old 2L-T wiring harnesses I would love to hear from them. I have swapped in a 2L-TII into an 1989 LJ70, and the harnesses and glow plug rails are a bit different. If anyone has any experience, with the 2L electrical system I would appreciate any...

I have been getting a PO141 on my 1996 Land Cruiser. It appears through my research that it points to the rear sensor, which as changed about 5 years ago. Just for kicks I hooked up my Icarsoft reader that I use for my Range Rover. This reader provides OBDII data streams. Interestingly the...

Hey folks, I've seen threads for people using the blue sea m-lvd (low voltage disconnect) for accessory loads like fridges. Would this also work for all loads? I'd like something like this that would also work if I leave a dome light on or similar. Any ideas? This is what Google produced...
