ST:TNG diverter coil stuck
« on: November 03, 2010, 02:31:50 PM »
Wow, this machine is killing me.

After problem after problem after problem in a supposedy fully working STTNG, my bottom divertor coil is stuck on to the extent its smokin. After a bit of research I may need to replace the transistor and resistor in the driver board corresponding to the coil. My problem is Jaycar only have 2k7ohm 1/2 watt (2.7kohm) but the board asks for a 1/4 watt resistor. Will a 1/4 be an issue? Can I just use this resistor? Any other ideas as to why the coil may be stuck on?

Many thanks for your help.

Common problem on the often problematic ST TNG. Before responding with a possible technical fix, you should notify the seller, as most reputable sellers should offer a shop warranty. A "fully working" machine should not have these issues.

The problem will most likely be on the driver board (Q15 or Q16). You should also tie the 50 V line with an additional wire as per Clay's Guide (3/4 of the way down this page);

You can use a 1/2 W resistor in the place of the 1/4 W resistor. You cannot substitute a 1/2 W with a 1/4 Watt.

Thanks for the Welcome.  <..>

I spoke to my supplier and he's going to take care of it for me.

I've fixed previous problems myself as I find working on these machines is quite satisfying. I think my ST:TNG may be the first of many.  &&

The missus is talking about moving the pin's to the garage, but if I play my cards right I might move the baby into the garage and setup the pins in the nursery.  :tumble: or maybe not.
