[Rhodes22-list] Solar Panel Output

[Bill Effros]

Jay,

Check out white/black color blindness--some people at the plant seem to have had some difficulty maintaining a consistent wire color scheme.  

On my boat, White is Neg. - Black is Pos.
However I've also seen Negative Circuits Black; Positive Circuits Red 
And I understand the new standard is Yellow for DC Neg.

So what is yours?  Don't answer too fast.

If something is attached backward it could be creating a problem.

Start by looking at your motor.

Bill

Thanks, Bill, I needed that!!!

Seriously, I know I have a short some place but running checks across 
all 6 circuits hasn't turned up anything. Without being able to isolate 
it, I can only compensate right now. I know the cells aren't losing 
much, just trying to hold what I can as a trickle charge. It's been 
on-going since 1997, with some rewiring by a local marina guy, and then 
at NC. Loss of voltage over weekend twice was after 1/2 hr.+ running 
time on motor.

Sat., I'll have a fresh set of eyes and meters. Next slip, an 
electrical engr. will help this weekend. Trying to do most of this 
without losing sailing time as well. You know what I have and it 
doesn't make sense-
it's not that complicated. Will persevere till I nail it.
Jay
