Dead Jet mini

Hopefully not to state the obvious but have you checked the little circuit breaker on the front of the VS box?

[Grant Wilkinson]

tks, Paul. I've checked it, and it is ok

I have the multimeter. That's what I have been using to trace the AC side. The problem with your next instruction is that I can't seem to find a step down transformer as one unit. Any AC to DC unit that I've seen so far ends up with DC in the 9 - 28 V range. Find the transformer in these units is easy.

However, according only to the motor, this one sends up with over 160V DC. Since I cannot measure any DC coming out of the terminals, I can't know what the spec of the board is. Jet doesn't say in the manual.

I've run the motor with 48 V DC, and can certainly confirm that, while it runs fine, it is nowhere near as fast as with the output from the controllers. So, I'm assuming the max input of the motor is pretty close to the max output of the controller.

As to the potentiometer, it is not getting any input. So, I know that fault is before that, but where? I have the pcb out of the case, and it looks pristine.

I'll see what Jet says tomorrow. If there is a cross border problem, I'll look up a used AC motor and simply put it on. I'll lose the VS, but I'll still be up and running.

Tks to all for your advice.

sounds to me Jet should put a better switch in it to start with.

I called VMH this morning, and they are great.

They are sending me a new controller board and a new speed pot.

The only down side is that they will take 2 - 3 weeks to get here!

Thanks to all of you for your advice. I really appreciate it.

Grant....it's good to hear that WMH is taking care of you! They've always been very good to me. I ordered a spare drive belt, a spare set of motor brushes and new handles that I overtightened.

A point of interest... A continuity tester for a switch isn't always an accurate method of checking its operation. A lot of switches will test good but can't handle a power load. Even light switches can fool you. DAMHIKT. The best method is to put a load across the switch.

Good luck
