No power on 2006 Maxum 1900 sr3

[Aaron303]

Good morning new to the forum and my 2006 Maxum 1900 sr3. Purchased this boat 3 weeks ago. Did a water test and boat was running.

This morning tried to test boat before taking it to the water but I have no power on my gauges or radio. The 12volt outlets have no power. The tilt for the motor works.

Inspected/checked

- run switch on throttle is on
- swapped out battery
- inspect all fuses under the dash ohm out ok
- checked for loose wires and reseated connections
- wiring diagram shows a 50amp circuit breaker mounted on the motor.
- I can press the button but not sure how to check it for continuity
- motor is the mercuiser 4.3 190 hp engine


Any hep would be appreciated

See if you have 12V on the B terminal of the ignition switch. No voltage check that the 10 pin circular connector is fully seated on the engine harness.

Appreciate the response. Tested continuity of the red wire going from the battery to the 50amp circuit. No continuity. I ran a jumper wire from the positive terminal on the battery to power connection on the 50amp circuit breaker. Power for the engine and gauges turned over. Must have a bad wire in the wire harness cluster.

I recommend you Google for the Mercruiser wiring diagram since they provide both the engine and helm harness. These are more accurate.
