Distribution Panel

[2ndwish]

Our 87 had the green DC indicator light and no voltmeter. It burned out several times and since we found it to be fairly useless, we replaced it with a small LCD panel meter (slightly bigger hole). Three years later, still works and now instead of trying to guess what an unlit light means, I can get a quick idea of the battery state by knowing the voltage. The panel meter was cheaper than the replacement light (which is actually a bulb) from Seaward.

Paul : after looking at your panel again, I believe that light is the DC power ON light. 
In most Catalinas that color DC power light is either blue or green, and NOT red (for a warning!).

Ron, it is red and was wired for power on. Checked it twice.
Thanks,

Do you remember the model of the digital voltmeter you installed?  How much bigger was it than the old voltmeter?

Paul : Most analog Voltmeters have a 2" to 2 1/16" cutout hole.

Pop your out and measure because there are digital voltmeters that are that size.

Order the new indicator light(green to replace the red) Installed today.  Works great.
