I have checked everything on my mc28, all the grounds,switches and still can't get it to fire. I did notice I never had anything going to the ignition coils. I checked for voltage, then used my multimeter which has a capacitor checker and it didn't seem right to me. I am an electrician and have check capacitors before, so I'm thinking the pgm is bad. I opened it up and the capacitors looked like they did have burn marks, or had been getting hot. I also notice 2 orange devices beside them (maybe resistors), but the covers or insulation had 2 cracks in each. Looking at the pgm there was nothing that looked totally evident it was bad. Would it be a choice of most of you to replace the pmg or try something else? I know this piece can get quit expensive, and could the pmg just go bad or is it usally something else that kills it? I guess I have to remember the bike is 14 years old. Thanks for the imput

The biggest killer of PGM's by far, is the poor maintenance of the RC Valves. Cables that are too tight, or gummed/coked up valve components put unnecessary strain on the servo motor, which then burns out the PGM.

The best and safest option is to see if you can try YOUR PGM on a known working bike. If that bike fails to start, then you have instantly found the issue, and can then work on why it has failed. If you try another PGM on your bike without finding the cause of the failure, it could be a very expensive couple of seconds!
