I'm going to throw this out here & see if anyone can give me the "Idiot's Guide to 12V wiring problems".
I decided to add an additional 12v light
in my 83' Burro
right next to the Heater Control (on the side of the closet). THere are 2 12 volt lights
on either side of the kitchen cabinets & they worked fine so this was simply going to be splicing into the existing black & white wires & connecting the new light
Welllll.... All was going well UNTIL... i accidentally touched the white & black wires together -- PSssfts! - the lights
went out -- all 3 sets -- the sink lights
AND my new addition.
I found that there was a single "in line" fuse under the sink that connected the Black pos(+) wire. I thought I had simply blown the fuse but, no. The fuse was replaced & still no lights. For grins, I bypassed the fuse by splicing the the black/pos wire together & still no lights (so, probably not the fuse, right...?).
I took my new light
& went outside of the trailer & touched the wires to the pos(+) & neg (-) leads on the deep cycle battery
. The light lit up - yea!
I went back in the trailer & tried attaching the wires from the light to the Black & White wires under the sink. NO LIGHT!
I went under the front bunk/couch area of the trailer (driver's side) & attached the wires to the 12 V Battery
wires (again, neg & pos leads coming straight off of the 12V Battery) &, VOILA, Light came on again.
1) While doing this, I noticed that the Neg (-) wire from the 12 V Battery
was capped where it entered the trailer & nothing was/is attached to it.
Why is this?
2) After attaching the light's wires to the neg & pos wires from the battery, I kept one attached to the black (pos+) lead from the 12V battery & the attached the other wire from the light to the WHITE WIRE ( the GROUND from the 7 pin connector) as shown in the Burro
Manual. NO LIGHT! If I move the wire off of the white ground & put it back onto the Neg wire coming from the battery, I am able to get the light to come on again.
3)Why do the 12V fixtures incorporate the white ground wire rather than utilizing the neg wire from the battery?
WHAT AM I DOING WRONG HERE ?????? Why am I not able to get the current flowing once I wire everything back up the way it was originally (Black Pos+ wire from the battery plus the White 7 pin ground wire)???
I'm making myself crazy over this!!!
Also, can somebody/anybody tell me what they think happened when I crossed the wires & originally lost lighting
? That would probably be helpful, eh?
PUHLEAEEEASE tell me WHAT IN THE WORLD I'M MISSING HERE!!!?????
This seemed so simple -- replace a fuse, get back to work, right? NOPE!
HELP PLEASE before I yank all the wiring out & re-run everything!!!
MANY thanks in advance for the help (please keep in mind that I'm no electrician when you send answers -- remember the "Idiot's Guide" part
