| battery charging | |

| Hey. Just got back from a 5 day camping trip which was all dry | |
| camping. Our travel trailer has two large 6 volt batteries which | |
| lasted us the whole trip. After driving home the batteries | |
| showed very little gain from charging off the truck. So my | |
| question is ouldint the batteries charge quite quickly off the | |
| truck?? I checked and do have voltage output at the trailer | |
| plug. The fuse going to the trailer charging harness from the | |
| factory is a 40 amp so I figure there should be lots of current | |
| there for charging. Does anyone one what amperage thier should | |
| be at the plug while driving? | |
| Thank you!! ::) | |

| Had a similar problem, [ 2-6v deep cycle ] we only do | |
| dry camping at a lake in the interior . fortunately, I had an | |
| extra 12 volt battery that I use for my electric trolling motor, | |
| upon returning home & plugging into shore power, I noticed that | |
| my panel was not showing a full 12v, so started to check fuses, | |
| found a 30 amp fuse was blown , replaced, now everything is as | |
| it should be. | |

| Was the fuse on the truck side or in the trailer? | |

| It doesn't sound like you have any issues, this is normal... The | |
| 7 pin harness on your vehicle will not supply more than a few | |
| amps of charging current to the trailers batteries while | |
| driving, which won't amount to much of a charge being put back | |
| into the trailers batteries (especially after 5 days of use). | |
| The wire size is too small and the wire run is far too long to | |
| supply a decent current without overheating the wiring. | |
| As a comparison..... My 6v's were at roughly 50% SOC yesterday | |
| when we left Shuswap. With 200w of solar on the roof of the | |
| trailer in full sun all day, and roughly 4 hrs driving time I | |
| still wasn't fully charged when we arrived home, and I did not | |
| expect it to be. I plugged the trailer into shore power at | |
| around 8pm yesterday and as of 8:40am the batteries are reading | |
| 90% SOC (my controller only reads in 10% increments). They | |
| probably won't read 100% until later today. | |

| The problem with engine charging on our class C is voltage. | |
| There were a couple of poor connectors and too long of a wire | |
| from engine to house batteries causing a drop of more than a | |
| volt. Lower voltage can�t push as much current into the | |
| batteries. | |
| A 100 watt solar panel solved all our charging problems. The | |
| batteries never go below 80% charge. | |
