Been struggling though assembly for a year now - gave up at one point but picked it back up this weekend to try to finish. All resistance checks have passed except terminals 1, 2, 4, and 5. My multimeter doesn’t pick up anything on them - just shows 1 no matter what I set it to. From everything I have looked at, they should get some value. Any words of advice? I can get pictures if someone directs me on which ones would be beneficial.

Thanks in advanced!

From the manual regarding terminals 1, 2, 4, and 5:

Also, the values signified with a * are going to vary from ohmmeter to ohmmeter because these terminals are connected to the filter capacitors, which try to charge themselves off the battery in the meter, causing a fluctuating reading. If the circuit is connected properly these readings will wander in the tens or hundreds of KR or higher range. What you want to watch out for is a zero reading at one of these terminals, which would indicate that something is mis-wired

Since you are not getting anything close to 0, there isn't an issue here.

A 1 reading on your meter probably means over limit, that is, the meter thinks the resistance is higher than it can measure on the scale it is set for. This would be the same as the OL reading that some other meters give when over limit. If it reads over limit on the highest scale that means a resistance in the Megohm range. For our purposes here that is pretty close to an infinite resistance, which fits the * definition.

This makes sense. I had some doubt when everyone else’s post seemed to show some sort of number other than 1. Appreciate the vote of confidence! I’ll proceed to the next steps
