use a test light for this purpose like Dan stated. A multimeter does not load the circuit and you can see acceptable voltage but not see voltage drop while under a load. If all lamp functions are out the logical place to look is the ground circuit. But make sure you check your bulb(s) as well...

Many people, especially garages use waste oil for heat. Relatively cheap, but more maintenance involved and it does not work well with oil contaminated with coolant. It is kind of dirty though. As far as blowing up your garage it would no more dangerous than a fuel oil furnace. BTU's should be...

The only logical conclusion is there is an issue at or within the AC switch in the controller. The AC and F/Rec LED indicators are on a different circuit than the AC switch to thermo amplifier so It could be multiple things wrong.

If you don't have ground on the W/B wire but do on the B/Y wire when the AC switch is turned on then you have an issue in the controller. The fact that the AC switch LED does not illuminate tends to indicate this. You are toggling the AC switch on and off while checking correct? Have you induced...

There should be a connection to ground on the W/B wire when the AC switch is toggled on. If not it will not engage the clutch. I would recommend checking continuity between each point in that circuit. If you ground the W/B wire does the clutch engage?

Do you have ground on the W/B wire or the B/Y wire off the controller, when the AC switch and the blower switch are on?

The thermistor is likely the sensor at the evaporator which should help prevent frost buildup and airflow blockage across the evaporator. The thermo amplifier is the controller which has the internal transistor the opens or closes the ground circuit as needed.

The W/B wire should be grounded with the blower switch on and the AC switch toggled on. The AC light should illuminate when turned on, if not it is likely there is no ground or the switch is bad. Is this so? Also is there power on Y/B wire (pin 4) of the thermo amplifier? If there is ground at...

You need a ground at the black with yellow wire when the blower is on. without this you will not have the AC light nor will the function turn on. This completes the ground circuit for the AC clutch relay through the thermo amplifier and through the controller. You do have the blower on when...

Can you post/share the schematic you are working from? That may help us help you. Also there is generally a section in the WSM that explains the operation and logic of that function.

As mentioned water intrusion generally causes the ball nut shaft bearings to fail which increase endplay in the shaft assembly. They can easily be rebuilt using aftermarket parts as long as nothing else needs replacement. If so it is usually better to try one of the aftermarket replacement boxes...

Being an electronically controlled governor there are no fuel adjustments to be made. The only thing that could be adjusted would be timing via the shims under the injection pump. You say smoke but do not describe the color. Is it greyish whitish in color? Diesels being a compression ignition...

I also forgot to mention that I would have the valves and seats checked or replaced on that hole. They are more than likely bent from interference.

Looks like a piece of wire or something in that shape. I would be checking out the air cleaner and intake tract for any possible broken pieces. As far as the piston I would check the piston height at TDC and compare to the other pistons. If the bottom of the piston skirt is broken it's very...

KMart is used by some in the construction industry to signify the Japanese manufacturers that either start with a K or some of the manufacturers that are based in Korea.
