Help! My favorite engine is malfunctioning!

It's possible that something is wrong with the tachometer reader on the flywheel of the motor. Some are magnetic, some have little slots for the LED to shine through, and some have stripes.

If you can take the boiler off and look at the flywheel, you should find the problem.

If that doesn't do it, follow the wires from the tach reader on the flywheel to where they plug into a board and see of one is broken, or the plug came loose.

You could have as many as six things that will give you problems. I would suspect the motor driver or the motor encoder is the culprit. If its one of these I would replace it with a ERR Cruise Commander "M" wireles tether. The "M" is not hard to replace. We are located in Norwalk Ohio and can assist you in your repair.

Bill,

I am located in Swanton, Ohio. I believe we are only about 30-50 miles apart. How would I go about bringing it to you for repair? Do I need an appointment? What is your address?

This is good news for me because I did not want to incur shipping cost on such a large engine (actually, I may have several that require some attention).

Thank your for responding!

Bill is most likely correct.  I would give the antenna a look.  Set your meter to continuity and put one probe on the handrail antenna and the other on engine ground.  If you get continuity correct the issue.  If you have this issue, the engine will take off like a rocket when you put your power up.
