Short in harness branson 3820.

[CR Jones]

I got a strange thing going on with the 2006 Banson 3820. Its an intermittent problem on the B side of the harness to the instrument panel. (Glow light, battery, oil indicators) it started with the glow indicator light, sometimes it worked and somtimes it didnt. Then the battery indicator light started doing the same thing, and then the oil temp light was acting up. Tractor runs fine no problems. But last week the temp dropped below 32 and a very very hard start.

The glow indicator was off. I checked voltage at the plugs and relay and everything was good except i was only getting 10.2 volts at the plugs. Then I noticed the bat light came on. I was only getting 12.6 volts at the battery while charging.

After didging around I realized if i unplugged the B connector to the insterment panel everything works great.

So i think i have a short or a bad insterment panel.

Before i dig into the harnest i just thought i would throw it out there to get some input. It would help if i could get a wiring diag for the harness and insterment panel.

Just a note: the battery light would turn on bright then after a few seconds the battery light would still be on but very dim.

Note: just realized this should be in the Branson Fourm, sorry my first post.

No worries. Welcome to the forum and you might pm one of the mods to move the post to the Branson forum.

Problem Solved: turns out the harness that rurns under the seat had been damaged by it rubbing on linkage over the years. The small short caused quit a bit of damage. The Insterment panel burned a run on the circuit board causing it to crack. That was easy to repair with just a little soulder. The rectifier blew out on the alternator and replaced with a used one. Also replaced the glow plug and glow timer relay. It runs like new now.

Hey, CR. I also have a Branson and live in Soddy Daisy. Do you get your Branson parts locally?

Good repairs, a bad harness can be a bear to locate.

No i got my parts at big reds. I bought a used alternator from a friend in Ringgold. I looked everywhere locally for parts and kept getting referred to a dealer in Rome but just decided to order the parts i needed on line.

In fairness to Branson the harness somehow came loose from the clamp that is suppose to hold it securely to the frame but somehow over the years got loose. I think it happened when some linkage was repaired a while back.
