Cs144???

[mrvette]

I have a CS 144 on a old motor home, as a vehicle it runs fine, pulls all the lights, charge, heater loads, fans, all of it.....

BUT with no other loads, engine at high idle, no fans, no lights, nothing but the battery and the HEI for a load.....

IF I fire up the new1200 watt power inverter, it's still fine, full voltage....if I turn on the small refrig....about a 600 watt load.....inverter pulls the alt down to 12.3 volt max output....

it's a junkyard alt, and been fine for over a year now...the regulator wiring is the L or brown wire goes to the dash light...no problem....

I added a new plug setup to it, to access the RED or Sense wire to the main power block....no help, same thing......

any suggestions??

Jeff?? B2B.....

Edit, don't bother, flixed it.....I thought I had the belt tight enough....it didn't even squeel or anything, so tight now I can play deliverance on the thing......

:gurney::thankyou:

With some simple math is possible to evaluate the power drain of the system:

Assuming your inverter have a good efficience, very close to 90%, 600W result as power drain of some 660W.

660W @ 12Volts is a load of 55Amps....... maybe more than the maximum alternator output!

OLD ET here, I just wasn't expecting a loose belt.....I put it on there last fall sometime about a year ago....new belt at that time...

While your at it, tighten the loose nut behind the wheel. :thankyou:

When your nutz hang lo, they wobble to and fro.....

but progress is being made....changeover relay wired so the fridge goes to battery power through inverter, only when engine is in run position....alt putting out, assuming belt is tight....rest of the time it's land power 110 campground....

not enough to drag the microwave....but can do fridge and some cheep TV's/etc.....

you all would be amazed to hear how cheep this thing is going together.....so far.....

edit, I can't remember if I commented in another thread or not....the inverters seem to be some sort of strange to me capacitor related charge/pump output making the a/c voltage....so it seems I can't ground the wide/white side of the output to the green/third safety ground....and so the previous owner/s had wired the breaker box with the isolated neutrals to the box/frame green ground/chassis and so I found the inverters would go krazy in that....

so to remove that bus wire in the breaker box, and float BOTH sides, IN THE VEHICLE ONLY.....when the changeover/ignition is dead, all the electricals then depend on the a/c plug into the campground wiring....grounding and neutral connected at THEIR box.....

but still all the battery negatives and outlets grounds are the same, just for the INVERTER alone, there is this floating neutral.....something I never expected....live and learn...
