electrical problems

Post by warren moore »

Need some help with an electrical problem. I have full power on everything except running lights and vhf radio, no power to either of these.I suspect a fuse for the running lights, but not a clue on radio.Both batteries are fully charged. Any suggestions or tips on what to look for to correct this problem would be greatly appreciated.

Check to see if the circuit breakers for the running lights are popping on the panel after you turn the lights on. They would be popped out. If so, then you may have a short circuit in one or two places. Yes, I have the unfortunate circumstance of having two short-circuits in the same electrical line for the bow lights once: one was in the bow pulpit just underneath the deck and the other was in the lamp socket. If you're popping CB's then look for shorts.

Since you're radio is also affected, there may or may not be a connection (no pun intended). You've got to do more checking. It could be a blown fuse in the VHF power supply line that you're not looking for or something wrong with the radio itself due to moisture or salt.

Warren,
Are the running lights and VHF led to the same breaker? If you are handy with a voltmeter check the volts at the breaker for each appliance and at the appliance itself.

Basicily, armed w/ your trust VOM (volt ohm meter), divide and conquer. Find a connection in the middle and check for volts (using the ground wire that the circut uses!!!) and see if you read anything. If not, go back to the battery. If yes, go towards the end. Have to use the ground that the circuit uses, as that counld be the bad one, and there is not other ground (it not a metal bodied car). I.E., the VHF, do you have power and ground at going into the radio, then you know where the problem is (radio or ship wiring). Its not rocket science, just a big loop that has to be complete. There is no one answer, as each boat is wired and run differently.
