Dead MRT MX Pro

[Elliott Hopkins]

Hello,

a friend of mine has just got back into racing and is using an MRT MX Pro.

Unfortunately he wired up his new batteries in reverse polarity and has apparently blown up the shottky diode and power cap and shut the speedo down. The last thing he saw when he reconnected the batteries after the pop was the led light up but then die off in a few seconds.

Is this a terminal problem or is there some way to reset the speedo to factory settings and bring it back to life?

Elliott.
