Installing new 6volt Batteries
New to this forum, but it looks like a lot of knowledgeable folks - Hope someone can assist me. I've got a 98 Dolphin 5360. Took the dead batteries out and forgot to see which cable (Black) and (Red) coming off coach is suppose to go to what terminal on the new batteries (Positive or Negative)? The Black cable is closest to rear wheels and the Red cable is to the right of it if facing the cables.
Any help would be appreciated.
Thanks!

If you have only two cables, and .... A source of 120vac, and .... A multi-meter.....
Plug in, measure voltage, the positive cable will be... Well,,, Positive.. most likely RED but don't count on that.
NOTE, insulate BOTH cables from any other metal before plugging in.

Where they are located has nothing to do with which one might be positive and which one might be negative.
As wa8yxm stated, insulate each cable from any metal objects and each other. Then hookup to shore power and hopefully your converter is turned on. Then using a DVOM or an old analog meter, place the meter in the VDC scale. Then place one probe on each end of the cables. I would try red to red and black to black. If the meter reads 12-13 VDC and not negative 12-13 VDC, then you now have your answer. if it does read negative, then the black is positive and the red is negative.

You said 6 volt batteries. You'll need to put a separate cable on the (+) terminal of battery one and attach the other end of the cable to the (-) terminal of battery two. The cable should be the same thickness as your red and black cables.
Then test your black and red cables as others have stated. It'll most likely be black to the (-) terminal of battery one and the red to the (+) terminal of battery two.
Hope this helps.

Take off any rings/bracelets/metal watches.... before you work with the batteries.

For Pete's sake don't connect them up wrong. There are no second chances.

I have, with my own eyes.
That is one of the reasons I never trust colors till I test.

From the factory no, however the infamous "Previous Owner" has skill/knowledge levels that are all over the map and may not follow conventions. Also "Quick Fixes" where the only thing available was used and never replaced.
Always check to be safe.

The cable that is connected to your frame is ground.
I am willing to bet BIG money Red is positive.
ANY takers
