Massimo 400 Buck electrical problem

[greendw100]

I have a Massimo 400 Buck that won't start. When I turn the key, I get nothing, no lights, the meter doesn't light up, etc... I replaced the ECU and everything lit up, it cranked perfect, ran for a couple of minutes and shut down again. I have tried calling Massimo, they are pathetic, have been waiting a week for a return call. Any idea where to look?

Are you sure it's not the battery? I had some issues with mine, and was fortunate enough to get with a tech at Massimo. He was informative and helpful. He emailed me the wiring diagram for my T-boss 410. His email address is [email protected]. I'm sure he can help. He's not real prompt, but he will get back to you.

No, it is not the battery, I have got it running but not sure why. I think there must be a contact sticking. I hit the voltage regulator with the handle of a screwdriver, everything powered up. the engine fired up and ran for a while then it shut down, had to hit the regulator again and it ran fine for the rest of the afternoon. This morning, everything fired up fine, I started backing it out and it quit running, had to hit it again and now is running fine. This is a new regulator, had the same situation with the old regulator.

Could it be the connections at the regulator? Or try to locate a regulator from another vendor. Could be it's a marginal part.
