The facts:
1978 FJ40 with rebuilt 2f and original (afaik) intake+exhaust manifold
There's a long story behind this post, but the punchline is that I have a bunch of exhaust leaks that I need to take care of. All of the gasket-oriented ones are no big deal. But...
Has anyone ever dealt with an...
Update:
Got another 60-series-compatible internally-regulated alternator installed per @Coolerman 's directions. Works like a champ. Figured out that the voltage drop between the alternator and the battery is because of the long run between the two. Nonetheless, my voltage at the battery is...
Only problem is that this doesn’t explain the voltage difference at the battery when I run a line directly from the alternator to (+) vs hooking up the original charging wire to the back of the alternator.
Sunnuva...(shakes fist)
@charliemeyer007 gets the gold star for calling it.
I detached all the things hanging off my positive terminal and tested each with my ammeter...When I got to the charging wire I got -2.7 amps. As soon as I removed the wire from the alternator end it went to 0.0...
OK. More data...
New battery installed. ...and drained overnight.
Any time the battery is hooked up, my ammeter shows a small discharge, even with the key off. I've verified that the needle zeroes out with the battery disconnected. I removed all the fuses. Still discharging. I removed the fuse...
The journey continues, but I've made progress...
I grabbed a compatible alternator with internal voltage regulator (searched for 1986 Land Cruiser alternator and ended up with this one, for future searchers). The thinking is that this eliminates a variable from the equation. To check things out...
Follow-up question:
Is there a compatible alternator with an internal voltage regulator? It seems like that could save me a LOT of time and frustration.
After spending lot of time studying wiring diagrams and measuring resistance across the wiring harness, I'm 90% sure that my wiring is just fubar'd. I think my path of least resistance (see what I did there?) is to just fashion my own harness for the voltage regulator.
Questions:
1. Does...
Right…more back story…
- new plugs, gapped
- new wires
- new cap
- new coil
- rebuilt motor (4 yrs ago)
- rebuilt transmission last year
- rebuilt rear diff last year
- fresh u joints
Nothing really changed recently other than changing the battery wire to the distributor to 10 gauge and...
FWIW I also just went and checked voltage for all the inputs/outputs to the alternator and voltage regulator (key on, engine off) and nothing unexpected.
Team, I'm struggling...
Context:
I have a '78 with the original 2f, Sniper TBI, and a HEI distributor. I've been chasing a misfire under load for a long time. I think it's finally come down to just not having enough juice to the coil. When I ran a bigger "bat" wire to the dizzy I got a big leap...
That’s helpful. But then I see this seal: Transmission to Transfer Case Seal for Toyota Land Cruiser FJ40 55 – JT Outfitters - https://www.jtoutfitters.com/product/transmission-to-transfer-case-seal-for-toyota-land-cruiser-fj40-55/
