my newly purchased Bigfoot
has turned into a bit of a nightmare....I paid a premium price for a unit that was advertized as "everything works" and "comes with two brand new 6 volt batteries".....that second quote should have raised a red flag.....
turns out, after having it parked and plugged in my driveway for ten days (assuming that the power center was charging the batteries, as it should)....I took it for a one night test run....I decided to check the voltage in the morning and got a reading of 11.82 (this is about 25% power left!) I was surprised at this because all I ran was a couple of lights
and a radio in the evening....and the furnace
cycled a few times during the night. I thought the whole point of having two six volts was to have gobs of reserve power...and that was not a lot of use in my book.
So I plugged the truck back in and drove off....some time later the voltage went to 12.4 then 12.6, that sounded promising, even though that is only 75% power or so.....so I decided to turn the fridge
on DC power mode....mistake, twenty minutes later voltage had dropped to 11.45 (about 25% power)....so I turned the fridge
off and continued along my way.
I got home plugged the trailer in and commenced to dig into this the next morning. The first reading I got was 11.84, after sitting plugged in all night all I had was 50% power? It only took a little more investigating to figure out that the charging side of the converter was not putting out any juice!
Somebody had gone to the expense of installing 2 six volt batteries....that never saw any charging time other than when the rig was being towed down the road, assuming that the TV was putting out current to the trailer, and I can't be sure of that.
I tried to charge the batteries back up but to no avail. I even used two different chargers, just to rule out the outside chance that the first one was defective! The highest voltage I was able to attain was 12.25...or about 50% power.....and as soon as I ran a few lights
for an hour the voltage started to plummet.
Two or three cycles/attempts at charging now have given the batteries the "coup de grace" I'm afraid.....coming home tonight after four hours of charging at 4 amps.....and the voltage is down to six and change.....the fridge
has quit, will not run in any mode (I suspect is has a low voltage cutoff of some sort,.... I hope)
So tomorrow it's off to the RV Service place I go....I guess.....then probably to the bank to get a second mortgage.....bummer.
I have one more option I suppose....I could go down to the battery
store and buy a good old, tried and true, 12 volt deep cycle battery
....then get a garden variety three stage battery
charger, plug it into the AC system and hard wire it to the battery.....monitor the thing myself.....the converter is still putting out good power AC and DC when it's plugged into "shore power"....and I know my truck it "putting out" when I'm driving down the road....
I'll have to sleep on that one......but a word to the "lurkers/shoppers" around here...if you're looking at an RV and the seller says something like: "Don't know much about RVs but everything seemed to work ok for me....." RUN, RUN AWAY VERY FAST....find a seller that knows his rig intimately (lesson learned the hard way). F
