No beep when DESS is connected – I picked up this boat in a trade with a friend because he could not keep it running and wanted to get rid of it. I don't claim any expertise. I just try to learn as much as I can and do my best with my limited knowledge. Any help/suggestions would be appreciated.
When I plug the DESS onto the receiver, I get nothing from the boat at all. Here is a list of things that I have done to try to find the problem.
Are there other tests that I should do to find this problem? I don't want to buy a new MPEM, then find I have another problem that destroys the new part.
Thanks for any help.

When I plug the DESS onto the receiver, I get nothing from the boat at all. Here is a list of things that I have done to try to find the problem.
- Battery charged – checks good 12+ volts. Note: I didn’t see the label that says don’t jump start or charge in boat. Negative terminal was disconnected the entire time the battery was being charged. I have read that jumping or charging with the battery in place can destroy the MPEM. With the negative cable disconnected, would it still wreck the MPEM if the battery was charged while the positive was still connected?
- After the battery was connected, the 15A fuse at the rear electrical box AND the 15A fuse at the MPEM were both found to be blown. I don’t know if they were blown before connecting the battery.
- Replaced both 15A fuses and reconnected the battery, the 15A fuse in the rear electrical box blew again. 15A fuse at the MPEM still ok. 5A fuse at the MPEM is good.
- Disconnected stator and replaced 15A fuse in the rear electrical box. Reconnected the battery and now the fuse does not blow anymore.
- Checked stator according to manual and got .5-.6 which is in range and not shorted out.
- Have not reconnected the stator because when it was connected the rear fuse blew.
- When DESS is put in place, not only are there no beeps, but no lights come on or any other indication of power.
- DESS pod checks out ok on ohm test per manual. 0 ohm with key in place, 1 with key not in place.
- Start/Stop button switch failed and will not close a circuit when pressed.
- Beeper seems to not work as I applied 12v to it, but got no sound. I hear these units are notorious for failing.
- Plugged the multi-tester into the leads for the beeper and plugged in the DESS. No signal from the MPEM.
- Disconnected the main wiring harness from the MPEM. Using the wiring diagram, identified the wire bringing power to the MPEM and verified 12v on the line from the rear electrical box.
- Identified the wire to the solenoid and a common. Disconnected the cable from the solenoid to the starter. Jumped the solenoid and common, the solenoid clicked and verified working. Reconnected the cable to the starter and jumped the solenoid again. Starter turned the engine over, but I did not keep it turning once I could see it was working.
- Disconnected the start/stop switch at the plug. Jumped the connector on the MPEM side of the disconnected plug in an attempt to close the circuit as if the start/stop button had been pressed. No response.
Are there other tests that I should do to find this problem? I don't want to buy a new MPEM, then find I have another problem that destroys the new part.
Thanks for any help.
