The fan is only supposed to come on if the unit gets too warm, so if you have it where it gets some air at each end that should be ok.

You are way better off with the LK for ever seeing the 14.6v that your battery needs at times. The LK will always start at 14.6 and do 30 minutes before dropping to 13.6v when in three-stage mode.

You likely have the unit installed where you can't get at it easily and from what you said before, you want to leave it in three-stage mode. It should be in that mode on arrival with the switch behind the left hand hole over to the left.

The pot behind the right hand hole should be left alone and should already be set for the correct three-stage voltages. If not, you can fix that, --see how to operate it here, para 10. (You need a flashlight and small screwdriver and a voltmeter in the output to see the voltage as you do the pot adjustment)

For accurate voltage "tuning" the unit must not be connected to the battery, or else the battery's lower voltage will drag down the voltage you see where the two try to "middle" their voltages. In real life, you can still twiddle the converter voltage up or down to change whatever voltage things are at now, but you won't be doing that probably.

If you ever get a different battery bank, you will appreciate having the LK which can be adjusted to meet any of the various battery charging specs.

Good news! Everything is installed and works well. What was advertised as an old PM3 is actually an LK version according to the label on the converter. Only disappointing this is the volume of the fan. The old piece of **** was quieter :-/

Yes, I realized the difference from our previous post. But like I said, old RV, not overly concerned about charging speed from the generator, cost less. Seemed a good compromise.
Thank you wa8yxm, that's my plan! I've installed a good number of outlets and I know better than to do anything less than use the screws and wrap the wire the correct way :-)

Well. I'd give you the instructions you ask for but.. Already got 'em (First response)

THe plan to put in an outlet for yoru plug in converter.. Great. May I suggest a 15/20 amp outlet 12ga wire from teh breaker and wrap the wires around the very well tightened screws.

The PM3 is the older version. The PM3 LK is the new version. They have somewhat different charging profiles doing their three-stages.
Won't matter on shore power at 13.6v, but the older version's can be slower to do a recharge from a generator.

You can tell them apart from the fan being external on the old one and internal with the new one.

Yes, I think I've got it figured out. Since the RV is a 1988, and it's an ongoing/never-ending project I compromised on price/needs and got the PowerMax Pm3-45.
I plan to wire an outlet from the breaker the current converter is on to plug the new one into.

Reviewed the old thread. I expect by now you know the "30a Rv" is 30a 120v while the 45a is DC (the converter's rating). So what converter did you get after all? Have fun with the installation!

You're the one who pointed me in the right direction last year. I finally got the deck mount converter in hand and plan to install it in the next couple days. Thank you for verification!

Yes. The new converter will only have one blue and one white, so the white goes to the same neg lug, and the blue to one of the two positive lugs which then is jumpered to the other positive lug.

Now the one new blue positive can run all the fuses instead of just some of them as before. Had to do that with our 6345 when I tossed the converter part and put a deck mount in there.

Only thing that went wrong is the brown flap door had no place to screw it on the bottom half anymore. Need to be creative there.
