I don't think it matters that much, at this point I just need to know what the thermo/top/top switches are and where.
I have been looking at other manuals, pretty much the same thing. However, in the other manuals they spell out things like " speed sensor" instead of something like "TOP S/W"...
Aha thanks.
I don't have an emissions manual. If there's one could you send me a link please. You think it would explain those three switches?
What would be so bad about connecting the dizzy vacuum advance to vacuum all the time? In my mind it's always positive (unless something bad happens...
I would appreaciate it if someone could explain what these things are: THERMO S/W, TOP S/W, TOP S/W. Which I have the smaller arrow pointed at in the following image:
Wow it has the same bracket and connector too. How did you find it? And way cheaper than the aisin vsv.
Thank you, see my previous reply please. I think it's an electrical issue as the VSV seems to function correctly.
Thank you. What I do loose if I bypassed the VSV?
I have new information. The VSV clicks when connected to a 12V source no problem.
I found the issue with the wiring, there's no power at the connector. One of the wires has a path to ground no problem, but I don't have 12V at the connector...
All the VSV's seem to have a constant source of 12V power from the ignition switch (see attached image). So, if this VSV in on all the time, would it be alright if I just bypass it altogether and connect the vacuum hoses directly?
I think this green VSV goes to the vacuum advance on the...
I have a FJ70 3F, one of the VSV's is leaking and hissing constantly. Part number is: 89570-35200
It looks like this one:

I found a number of AISIN VSV's on amazon.com with a different connter style, what's the difference...
Well the problem is sneaky* and difficult to diagnose for sure. I have narrowed it down to the the starter solenoid. I bought a used solenoid from another Toyota car that fits my starter but didn't install it yer because the problem suddenly went away! Whether this fixes my problem, or whether I...
Hello
I really need to install a relay between the starter and the ignition switch. The circuit goes through the ignition switch itself, the OEM switch wires melted from the heat, the new aftermarket one got really hot today.
I would really like to bypass the switch itself, I know it can be...
This is not my main issue, but here's the information if helps the problem in this post.
I have an aftermarket stereo with the radio antenna disconnected, I listen via bluetooth only. And I have an FM transceiver.
Now, while listening on the transceiver I have no issue, but there is static...
I have one small device that does that, it's located on passenger side near the battery and under/behind the air filter.
I just don't know which kind the OEM plug wires are classified under. I never read that people had to change them with pertronix ignition in these trucks (FJ70 FJ60 3F), so...
OK so according to the FSM (chassis and body) pages 715-716, this wire appears to go to either the AC amplifier or the tach (my truck wasn't supplied with one). In any case it doesn't seem relevant to my problem. That wire is definitely a positive wire after further testing.
This leaves me with...
At the time of measuring the voltage in that wire, it wasn't connected to anything. I did not connect it to the coil, it was just dangling. I have no idea why it behaves that way. So I don't think it was affected by the coil at all. Keep in mind that my wiring has slightly changed after...
I'm reading the FSM, the wiring diagram in IG-3 shows that that wire should be a ground. But why does it appear as a positive on the voltmeter when the engine is running?
Hi
I installed Pertronix igniter ll on my 1990 FJ70 3F, I removed the condenser and the resistor. I screwed both resistor wires to the positive side of the coil.
The truck work fine, except I had to rotate the dizzy all the way that I could, 22 degrees.
There's one wire that I haven't...
Since I didn't touch the dizzy timing, I played with it. I pushed it all the way to 22 degrees and it was still improving. I couldn't push it any further because the dizzy cap clips were physically touching the engine, I can't spin it any further than that.
If the ball was 7 degrees, and I had...
