Intermittent power loss
For the second time recently my 2004 Duffy 21 Classic stopped responding to the throttle in either direction...foward or reverse. After swtiching off the ignition and waiting several minutes it started responding again. What could be the problem?
Hi Ed, the likely suspects are the throttle and the speed controller. Here's a write-up of a throttle rebuild, as well as a description of some of the symptoms:
Thanks. I’ll check this out.
Happy to help. I expect most electric motor shops would have no problem rebuilding a motor and diagnosing the throttle/speed controller.
I'm using Alltrax XCT speed controllers on both of my electric boats. Neither boat came with the stock controller, and I found the Alltrax really easy to program with a laptop. For throttles I'm using single axis joysticks like the JR Merritt Pro-4. The Alltrax controller will use several different kinds of throttle, and you just tell it which in the programming software.
