Hi,
Just got a Viper CV68 and want to fit a battery in it. (None in it when I got it).
The problem is the wiring to the battery box is Black and White with no indication as to what polarity each wire is. Any help would be much appreciated as I don't want to 'fry' any electrics if I guess it wrong,
Cheers James.

Don't make any assumption based on color! I've learned that with my 1537. Normally one would expect black to be negative, but not necessarily so for some reason in some random Ovations.

Look very carefully at the box itself. Where the terminals of the battery slide in, one slot may be slightly larger than the other. This is how mine is. It is difficult to see without good lighting. The battery itself has one larger and one smaller terminal. They should fit the slots in the battery case.

FWIW, the wrong polarity shouldn't damage the electronics, though your caution is a good thing. I won't guarantee no damage, but would be surprised if the circuit isn't diode protected.

FlySig,
Many thanks for your input however with a strong light and more powerful glasses I found a small + on the white wire terminal so all is well.
Once again many thanks for your suggestions.

Amazing to say the least!! With house & automotive wiring black is always positive. White is always negative.

Not necessarily...

house AC wiring - black = hot, white = neutral
auto DC wiring - red usually pos, black usually ground. (at least at the battery)

The battery box in my '97C has red and black wires. The red is negative, black positive! Totally backwards for audio electronics. But, the terminals cutouts in the box are the correct polarity for the large/small battery terminals. Goofy.

@FlySig - "The red is negative, black positive! Goofy."

It sounds like the electronics factory was working in the dark that day.

Black is Hot. White is Neutral. Green is Ground. Red is a Switch-leg.

You're welcome.

As one who has had to do a lot of soldering, best is to always...ALWAYS...put a meter on it...at this level errors just result in an item not functioning.

On tours when you hook up distribution systems to the feeds in the arenas, while there are color conventions for the CAM-Lock connectors, get a hot and a ground mixed up because of color and you have fried 10s of thousands in amplification racks and 110 circuits to the instruments. Put a meter on it.

For the record - in these scenarios the Green = Ground, White = Neutral, Black, Red, and Blue are Hots in a 3-phase system - usually 200Amps per leg - which if you screw it up - will do more than fry the hairs on your tongue.

All my cars seem to Red = Positive, Black = Ground/Negative
