Like I said before I would rather remove all of this BS wiring from the board and do it right instead of trying to figure out what they were doing here. I could follow the instructions and build it back to stock but I know some jumpers have to be added for the 420a motor. I plan on only running fuel right now till I get the hang of this thing then adding spark in a month or 2. I also would like to have the ignitors built into the MS and not have to use an external transistor pack. Xtreme could you take a few pics of your board and post them so I could compare the difference between them and alter mine according to yours?

The jumper wire at LED 18 is connected to both the led holes? The negative and positive? By both holes, you do mean where the legs of the Led would solder to, correct? If that is the case, then man, dont ever power up that board! I would de-solder all that crap that goes to and from LED 18, you dont need it or want any of that at this point. Before you unsolder all the other jumpers, you should look at the MS1 420a input/output schematic mods and see if it's done right. No point in de-soldering all the mods if they are already correct. I mean, you will need to know how to follow the mod diagrams anyway, so get that figured out.

I can take some pics, but my camera isn't the greatest for closeups..I'll see what i can do. It will be hard to follow from a picture anyway, nor SHOULD you. If you can't figure out how to read the schematics and do the mods, then you really should find someone who can. Frying these boards isn't all that hard to do if you don't know what you are doing.
