i have a premiere F3 engine that has been altered to flip the start out direction so it runs as a powered rear wirh another separate powered front F3. The motors leads have simply been reversed successfully, but unlike typical diesels, the directional lighting to this board is soldered in place by a blue and brown wire. It doesn't just plug in to the blue or green sockets on the board. Never seen this before!
How do I flop the lighting direction with it soldered??

You could probably run the light directly from the motor wire leads with a diode so it only lights up in one direction....You wouldn't have constant lighting though.
Is this a slave board?
OK, never mind everyone I FOUND A WORK-AROUND SOLUTION, as I was out of time.
Since each PS1 board has designated blue and green plug-in leads on the board for front and rear lighting, which MTH did not use on these F3 guys for some reason, I realized - why not just hook up a 1.5v bulb to a spare plug-in prong cable and - BINGO - plug it into the green plug-in lead since forward is now reverse. Voila, works like a charm!
I'm a genius!
OK... not really, but just happy. Whew!
THat is because the engine has a CV Board to run all the other lights including a MARS if so equipped. The board use a motor power sense to trigger the on and off of the directional lighting via the CV board. You could move those wires over to the corresponding pins on the other side of the PS-1 bottom board. But that is typically where the slave unit pick up comes from. Since this has been modified for different directional operation, your method is probably better. G

Good info. Not knowing if the included directional bulb was safe for 1.5 volts, I just didn't want to risk plugging it into the blue or green terminal and blow something up. I simply unhooked red plug leading from the soldered points on the board and left it there (in case a future owner wants to go back to he factory set up). Adding in a new 1.5 bulb to the green terminal was just faster and safer. I only had an hour to figure this out for client lol
Seeing as how I was 7 when these were released I've been self-teaching on these QSI boards lately. I've got them mostly down, but things like bulbs they used and what's safe voltage draw or pull...sometimes I don't want to find out the hard way. I have no diagram, no technical data from QSI - just you guys and my own instinct. Thanks for chiming in.
