Customer Question

Hi. Fir the first time ever, I'm having symptoms of a short. How do I get to the botttom of it? How do you diagnose it? I double checked battery terminals and even took off all light bulbs off cuddy lights. Any thoughts? We're stationed in LB and off to our fist Catalina Island overnight day after tomorrow but now not sure. Thanks.

Welcome,this question may need more than a single answer. Please post back with additional questions on this at any time.
I need a little more information as to what you think is shorting and what the symptoms are? What circuit or devise is not working? Do you have a voltmeter capable of reading resistance?
Post back and we'll get started on this.

Hey Jeff. Everything worked fine when I first turned on yesterday then out of nowhere all the lights went out. Now docked and plugged in and still nothing electrical works. New bilge won't work, lights don't turn on. Engine turns on and some gages work but when I turn something like the courtesy light switch or navi light switchup or "on" gages stop working. Like a short happens or something. Super weird.

And no, no voltometer just the volts gage. Which seems low like 8-9 volts. Thanks.
