Need wiring help on wiring a 1994 Marine Air system to a Cruiseair SMXII control box

I am trying to connect an CRUISAIR SMXII power logic box mdl. A-285 (and digital thermostat) to a 1994 MARINE AIR unit mdl. VHTK16K-H. There are slight color differences in the wiring between a Cruisair and Marine Air. The original unit (which I have removed) was also a Marine Air unit and had a terminal block on the top of the unit. This is where two (2) line feeds came in and terminate. One is the main power feed. I am not sure where the other goes? To the thermostat maybe?? The unit I am installing is a 1994 unit which has no terminal block on top. All of the wiring is in a bundle. The wire colors on the MARINE AIR unit are: GN, BK, WT, W/B, Red, Org, B/R, Y. The wire colors on the CRUISE AIR control box are: GN, BK, R/W, Org, PURPLE and BLUE. There is are separate wires coming from the control box which are BK and Blue. The blue wire is for the high pressure switch and the black went to a ground originally. There is a three color main feed: BK, WT, and Green. There is another BK, WT and Green which should supply power to the raw water pump. Any assistance would be appreciate. I have already discovered that wiring it up the way it came out only triggers the circuit breaker. I only tried that once and hopefully did not damage the motherboard. Thank you, Emory

SOURCE: Unit trips circuit breaker when plugged in

On AC current it really makes no difference to the operation of the unit which terminal the wires are connected to as long as the circuit is completed. A reason for the inverted wiring is that there will be a resistance between the hot wire and the control circuit. It makes for a reduced load on the contacts and switches minimizing arching.

SOURCE: Manual Thermostat replcaement with Programmable Digital unit.

Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters

You have a "Multi-Tap" transformer, and should have a white label on it with wiring.

SOURCE: a duo therm thermostat (p/n 3105058) was removed

a. Remove the cover of the thermostat.
b. Connect the RED wire from the air conditioner
to the “RC” terminal on the thermostat.
c. Connect the “YELLOW” wire from the air conditioner
to the “Y” terminal on the thermostat.
d. Connect the “BLUE” wire from the air conditioner
to the “H” terminal on the thermostat.
e. Connect the “ORANGE” wire from the air conditioner
to the “G” terminal on the thermostat.
f. Push the thermostat wires into hole in wall and
fill excess hole with insulation.
g. Mount thermostat base to the wall with screws
provided.
h. Check all thermostat wires on base to ensure
they are completely clear of the bimetal coil of
the thermostat. Adjust if necessary.
i. Replace thermostat cover.
If nothing operates on the air conditioner, remove the
return air grille assembly and verify the red, orange, yellow
and blue wires are properly connected (red-to-red,
orange-to-orange, etc.).
Next, disconnect the red wires and check for 12 volt
DC between the red wire from roof section and the orange
or blue wire from roof section. If no voltage received,
refer to Section F2. If voltage is received, the
problem lies with the thermostat or thermostat wires.
Next, disconnect all 4 wires (red, orange, yellow and
blue) from the thermostat. With the thermostat set on
COOL mode, FAN mode set on AUTO and HIGH, and
temperature selector set lower than the room temperature. Check for continuity between terminal RC (red wire)
and terminal G (orange wire); and RC (red wire) and
terminal H (blue wire). If continuity is achieved on each,
proceed with the next step.
Set fan switch to LOW. Continuity should NOT be present
between terminal RC and Terminal H, but present between
the other terminals (Y & G) and terminal RC.
If all of the previous checks are good, the thermostat is
good, do not replace it. If any one of the previous checks
are not correct, replace the thermostat.

How do I reattach the tube that leads from the light button to the air switch in the control panel? I can not find the air switch.


First of all, possible correction to the other answer...
If you have a Circuit Board, you probably do NOT have...
  • Air Button
  • Air Switch
  • Air Tubing
And, if you do have ...
  • Air Tubing
  • Air Button
  • And Air Switch
You probably do not have a Circuit Board!

Most commonly, circuit boards are on an Electronic control system. Air buttons are associated with a Mechanical control system.

Now, let me do my best to try to help you out here, lets say you do NOT have a circuit board (per your description of the problem in your question) and you do have an Active Mechanical system that utilizes an air button with tubing to a air switch/sensor.
That air switch will be normally installed in the control box, along one of the vertical sides, rarely are they on the bottom or back. I have never seen one on the front! They will have the nipple portion of the switch (the part the tubing connects to) protruding thru the side, so the tube can connect to it.
The switch will look something like...

25733123-behugfiqwutr4zayjk2rtvrx-5-0.jpg Or...

25733123-behugfiqwutr4zayjk2rtvrx-5-1.jpg Or it could be a multifunction switch, but possibly not for a light...

25733123-behugfiqwutr4zayjk2rtvrx-5-2.jpg Now, sometimes - some spa manufacturers utilized a completely separate system for the function of the light! It does not have the air sensor/switch within the main control box! That could be the reason you can't find where to put the air tubing? So if your system is Mechanical, you may have a separate transformer with a built in air switch off somewhere in the equipment bay? It will be a small unit with a black wire and white wire (small gauge) going to the light bulb, and a bigger sheathed wire that will be going to the control box for a 120v power supply.
It will look something like this...

WHERE DO I WIRE THE 24VAC CONTROL WIRING TO THE CONDENSER ON A LIEBERT 3000 air-cooled system at the condenser????? the manual is not specific


The control wires need to be connected to the power relay in the electrical box. The power relay is the switch that feeds hot 220vac to the cold side of the compressor and internals 220vac side.
Hope this helps. Kind of generic but should be obvious after you open the electricals cover. There is probably a wiring diagram on the inside cover.

My Mercury Outboard will not turn it seems like I am not getting power to the Control Box, or the Switch Box? be cause I can take a wire straight from Battery to the red wire that goes to control box and...


I think the control box receives power directly from the battery and when the key is turned to the start position, activates the solenoid and then the starter. I have had about a dozen Mercs but don"t recall a wire from the control box to the rectifier.

Cruisair marine ac trips breaker


Compressor motor is stalled on start up which trips breaker. Try changing out the start capacitor. Its supposed to change the AC phase to enable more starting torque on a stopped motor.

I have a jbl mr-145 in a hot tub. It keeps powering on and off???


I have the same model stereo in a brand new hot tub that was having the same issue. To fix it all u need to do is pull the front cover off to access the pump controls and in there you will find a black box where a power cable runs yo the stereo. There are two screws that open a little door in the black box. In there you will need a small flat head screwdriver to move a redswit over to the 110 volts position. Turn the radio on and it should work. That black box just controls the power to the stereo.

1994 Jeep Cherokee 4.0L AC wiring


Hope you can read it? If not I'll try something else. See the compressor relay, that line with arrowhead is load side of relay, when relay is energized that arrowhead moves to other terminal, that is a fuse protected circuit, goes hot with the key on, underhood fuse box/power distribution center f6--15amp. The left side of relay is control, needs voltage and ground. fuse f5--25 amp interior fuse box and is wired through selection switch. As you can see, the computer grounds control side of relay.
Your second paragraph sounds like a big voltage drop, somewhere, I'd have make sure battery is good and charged up, check battery connections and check your charging system.

Air Function In Honda Accord Wagon - not working


Check your fuse box for any blown or old fuses. Could be under the hood in your fuse box or under the dash inside the car. Check to see "visually" without the car running or power on, for any damaged wires or connections throught your climate control system. I dont know the history of your car but if any wires were cut by chance from someones negligence" installing a stereo or other accesories" may have led to this. Perhaps it could simply be the fan switch for the climate control or a relay switch gone bad.
