PS2 Smoke Unit No Heat Problem

10 ohms is about right. Nominal resistance across the elements is 8 ohms, but the wiring will add a little more.

I would measure the voltage across the elements with the engine fired up and the smoke unit on. You should see a few volts DC.

If not, you either have a wiring issue, or your board has a fritzed FET. 

Perhaps GGG or someone else knows which components on the board are at fault.

I have tested the wires back to the PS2 board. The brown wire from the heat element is good to the board. The purple wire from the heat element is fed from the white and yellow motor leads, in the engine, thru diodes. The electrical path is continuous. The motor runs so the purple is OK.

So it appears that the problem is in the PS2 board. Does that make sense?

What would cause the board source to the heating element to stop functioning?

When you modify the smoke unit for PS/2, you remove ALL of the electronics and run the fan and smoke resistor directly.  If you have the correct smoke unit resistance at the PS/2 PCB connector, it sounds like you either need a reset of the PS/2 electronics or perhaps you have toasted the smoke output by shorting it to frame ground.

I am very interested in hearing what you find out on this.  I have a ps2 pacific that might have the same problem.  Everything looks like it should work, but no heat.

It turned out that there was nothing wrong with the smoke unit or anything else.

All it needed was a new wick. The old one was fried. Now it smokes like a Champ.

One of these days I will check the easy solution before jumping to conclusions!

Thank you all who spent time on this.

:-)  Good news! G

That's good, since you said there was no warmth from the stack, I figured we were beyond that.  It's nice that it was an easy one...
