Hi,
Yesterday, I decided to convert 2 of my Williams diesels(GG-1 and GP-9)to series wiring. I did this for a few reasons. One...both those diesels pull a line of MTH passenger cars and they barely illuminate at the low voltages that those diesels previously ran at. 2.....I recently bought a PW Lionel NW-2 switcher and really like it's low speed crawl. My Williams engines take off like jack rabbits. So, I found Joe's directions for the wiring and went at it. The GG-1 went well and I got the performance I was hoping for. My GP-9 was not as easy. I wired it up and it didn't work. Wired it again and it didn't work. So, I compared the connections on the circuit boards of my other engines and sure enough....a blue wire should have been yellow and a yellow should have been blue. Colored wrong and connected wrong (from the factory). I straightened it out and did the wiring and it works.
Anyway....reason for this post.....I would like to put a switch in that will enable me to switch from parallel to series and vice versa without having to unsolder and rewire. I need to know a couple of things. I've been searching for a switch that can handle this. I figured it would have to be some type of double pole, but haven't had any luck locating something small enough. A knife switch would work, but they are large. Second....how would the wiring work connected to this switch? Any advice about this will be welcomed.
The only downside of doing this series wiring that I can see is that I will have to be very careful about not giving it too much juice (I use a ZW) which will probably blow the big, 5 surface LEDs I have in those engines.
Thanks,
RNF
