Default Check your cables

On trip from Shipshewana to our nephews place here in Michigan both dash volt gauges started bouncing.
Checked alternator output and it's 46v. Ouch !!
Removed it and that's when I found the negative cable about burnt thru. See pic.
Replaced alternator, ground cable, battery isolator and now it's all good.
So did the bad ground take out the voltage regulator or did it just fail after all these years ?

bad/no ground output goes/shows very high most alternators will put out/show 100 volts or better with open ground i worked on a coach that showed 100 volts or so,,, we found bad ground - corrected it all was well.. ground issues are not uncommon with coach that has a few years on it. on our current coach i replaced most of the cable end as they were corroded inside the cable ends and had resistance across end to wire,,had to replace most cables too as after shorting cables past corrosion they were to short,,,
just food for thought ..

Do my eyes deceive me or does that failed lug look like it was soldered on?

Considering the cost of the repair, purchasing a decent crimp tool and learning to do the connections correctly would be way cheaper.

Sure does look like it was soldered.
It could have been original but no way to know that.
My nephew trashed it or I could have cut it apart .
Rest assured friends there is no solder on its replacement.

Default Cable crimper

Gents and Ladies

I just posted a reply to one of our Colorado members about battery cables.

At our shop in Longmont, we have a bench mounted hex crimper that will handle crimps up to 4/0. We sell cable and ends, and would be happy to supply them at the 10% WOG discount. However, we are just off I-25 and would let our friends use the crimper even if they bring their own parts. If you need work done “on” the coach, we have portable crimpers as well. Since there are only the two of us, please call the shop before stopping. The number is 303-682-0755. We usually have space for one coach for this kind of work.

We know the crimpers are expensive (we sell them, too),and hope this can help some woggers with the added expense. We also hope to meet and make new friends.
