    Question ALUMACRAFT 1860 Owners ???

    I am trying to diagnosis why my gauge lights do not come on. All the bulbs look good, No brker's tripped, and I get 12V on each gauge between the Blue wire lug & the ignition lug on the back of each gauge. Can anyone one tell me HOW or WHEN the gauge lights illuminate ?
    Thanks for any helpful info...

    That didn't work. I did pull the sockets on the nav lights 0 volts on the stern, .06V on the bow lights.. Interesting. Perhaps my two issues are related. I believe I am pissing in a fan. No Idea. Maybe I will start at the Brker & see if THAT has power..

    Sounds logical. Trace the power back and see where you get voltage.

    Problem solved.. I found a spade connector came off and a BAD Breaker. Everything works.. Yes, I need to replace that breaker permanently.
