I'm lighting my 1/350 PL Refit - I'm using CCFT's in each nacelle - each with it's own inverter. When I hook up both to my Radio Shack 12V 1.5amp power supply, one dims.
If I hook up each one by itself, both are fine. The problem seems to be with the right one - I'm wondering if a bad solder connection at the inverter circuit board would do this. I removed the wires from the inverters and directly soldered the leads from the tubes to the board - did the same with the power leads to minimize wire length.
I also had to replace one of the inverters because it died. I don't know if the new one is the problem or if the dim nacelle is the old inverter.
I am running the full 12V (really close to 15V...) using 18 gauge wire right to the nacelles (I've isolated them from the rest of the model for testing) -
Everything else is working great. When I hook up everything (the saucer, etc), one nacelle lights brightly and the other is dim. (That's when I decided to isolate them to narrow down the issue.)
I should have plenty of power to run these things. Any suggestions? Wild guesses?
One thing is for sure. They are gonna be a pain to crack open again - I epoxied those mothers!
