Fixing jumping voltages from the R/r

Referring back to this thread http://www.thegsresources.com/_forum/showthread.php?t=197281

I believe I have sorted the problem which seems to have been a lack of good ground from the R/r. There was one ground wire coming from the R/R (green as its a shindengen from a Honda) which I connected to the battery negative and the body of the unit was bolted dirctly to the frame and made a good metal to metal contact. Apparently not enough , however, as the voltage kept jumping.

Thinking about what the folks have said it seemed to me that grounding or rather lack of grounding did indeed have something more to do with it.

I didn't like the ring connectors I had used to fix the groundwire and source wire to the battery so I changed them out to something a bit more substantial. It didn't make any differenc as the voltage kept hoping about once again.

As I was checking voltage again with the multimeter I thought to touch the black ground probe directly to the R/R body and instantly everything settled down and I realized my grounds were not good enough. To check that I was on the right path, I made upa short jumper which I ran from the battery negative to the body of the R/R at its frame bolt and once again I have good steady in spec voltages from around 13v at idle to 14.5 at 5000 rpm. Good enough for government work so hopefully that is it.

In the next day or so I will tidy this up a bit more and will tie an extra lead into the R/R ground which I'll take directly to the frame and then with 4 paths I think I should be good for grounds. The fuse block does need some cleaning up too I'm sure and I will attend to that in due course.

Once again , many thanks to all who contributed I couldn't have sorted this out without y'all ( I think I need a mint julep or something as the southerner in me seems to be coming out).

Cheers all,

If you were that Southern, you would have moved east to that city that was founded by a Southerner, ... Montre-y'all. :-\\\

Hey, what about the "Send koolaid_kid to the Bahamas" fund? ;):D:dancing:
But seriously, congrats.
Jim, posplayr, believes in sending all grounds to one central location, then connecting that one location directly to the negative terminal of the battery. Not a bad system, and empirical evidence supports it, although a string of 3-4 ground posts all connected together and then going to the battery may accomplish the same results with less hassle.
 
Great news...very helpfull as I will be installing my new R/R next week. I will double check my grounds and get the little dremel out and get some nice shiny metal!

Mint Julep???
Really?
You couldn't have picked, say, Jack Daniels or Southern Comfort?
Oh well....have a beer instead.
Cheers
 
When I was having similar issues I tried moving the grounds from the batt- post to a bare metal spot on the frame, then one single wire to batt-. Everything was much more stable once I understood that the electrics work best when the return path depends on the frame and going through the battery isn't the most direct path. So put the connector from batt- closet to the frame, then you can mess with other electrical stuff without having to disconnect the battery all the time. Looks cleaner too.

I might just do that when I install mine. Put the neg. ring right to the frame, and the battery right to the frame. Give it a good coating with grease and Bobs Yer Uncle!!
Less wiring is always better AFAIAC. And, it is easier to remove the battery.
