PT-42 Front Heaters

[Kurt Horvath]

Well now I feel stupid, Tom is right, it is a heater for the Aqua hot and if I'd
have looked past my nose I would have seen the heater core from the CB
compartment. I took the little compartment below the draw / cup holder out.
There is a covering, plywood, above the heater core. There was a large tangle of
wires and the control box for the musical horns and a wiring loom, all of it was
just lying on top of the fans keeping them from operating. I moved everything
out of the way and it is functioning fine.

But as you know for every action there is an opposite and equal reaction. There
are several things that are not as they should be. Fix one problem find two more
needing attention. There appears to be an alarm system and two small boxes one
of them appears to be a remote controlled relay it has a 10 pin harness, I
bought a similar device to control the cooling fans I’m installing in the engine
compartment, the second box has a turn screw control and a light, it has a three
pin harness, the switch is labeled: Alarm System it has three settings: Mikes
On, System Off, Mikes Off. The wiring harnesses are not hooked up. I’m not sure
if all of these pieces are related or are for different systems. I was told the
coach did not have an alarm system when I bought it but that appears to be
wrong.

If some one could tell what this stuff is I'd appreciate it. I'm hesitant to
just plug everything in and wait to see what happens. The last thing I need is
an unknown system shutting down the coach when least expected.

The larger vent up front should be controoled by you AquaHot Gas
heating control near the middle of the coach. If you do not get heat
there, your circulation fan must be out.

My slider for the dash temparature control is also tight. Let me
know if you find a way to make it easier.
