ONAN 5500 Installation. On a normal ONAN 8-pin wiring harness the cables are labeled in the harness the following:

Here are typical installation guidelines for an ONAN 5500 Gas/Diesel/Propane with a 8-pin generator wiring harness.

Note: For action 7 you’ll want to buy 14-gauge electrical cable for the run from our ShorePower track to your transfer switch.


Turn-off your generator AC circuit breakers in order to avoid disruption of coast energy solution during installation and evaluating of ShorePower track.


Recognize the following 4 cables on your own generator wiring harness.

Work with a tape or label to mark each cable so that you won’t forget which wire is which.

  • A – Ground – Brown
  • B – Stop – Green
  • C – Begin – Red
  • E – Run – Orange

The wires are labeled on the harness as follows on a typical ONAN 10-pin wiring harness

  • A – Ground
  • C – Begin
  • E – Stop
  • F – Run

NOTE: The pin connections above are typical ONAN connections. Only a few ONAN generators have actually the generator that is same harness connections as some might have been changed because of the dealer or RV maker. Make sure you have actually precisely identified the 4 cables precisely before proceeding with step three.


Connect one Posi-Tap to each of this 4 cables identified in step two.


Make the connection through the ShorePower track towards the Posi-Taps (wiring harness) depending on the wiring diagram supplied.

  • Green cable to E AVOID
  • Red wire to C BEGIN
  • Brown wire to A GROUND
  • Orange cable to FRUN

Be sure to link the proper cables to the wiring harness even as we utilize red-colored wires over and over again.

On our installation picture we utilized wires that are white extend towards the harness as a result of location of y our product. The closer the installation of y our product towards the wiring harness will assist you to make use of the provided 4-foot wire size we offer.


  • Link the red cable from the ShorePower Monitor (I3) to at least one region of the enable switch utilising the provided Posi-Lock or perhaps a crimp connector.
  • Link the 2nd red cable (supplied in the zip-lock case) to the other part of this mail order bride switch that is enable. One other end of the red cable will sooner or later get in touch to your good battery pack terminal.


  • Link the red cable through the enable switch as well as the red cable from (L+) from the ShorePower track to your +12 VDC (good battery terminal).
  • Link the wire that is blackM) in the ShorePower track to ground (any steel on the RV).


Through the ShorePower Monitor Power Converter ( See wiring diagram B – Transfer Switch Connection):

You will need 14-gauge stranded wire that is electrical the run from our device to your transfer switch.

  • Connect (L) on our MeanWell Power Converter to at least one part associated with the 110 Volts regarding the transfer switch.
  • Link the (N) on our MeanWell Power Converter to your center connection (common) regarding the transfer switch


The ShorePower track & the MeanWell Power Converter should both have their green light in, if all of the cables, such as the cables towards the transfer switch, have already been properly linked. .

  • To try the machine turn the ENABLE Switch ON and disconnect from coast energy. The light that is green the MeanWell goes off and in more or less 20 moments our product will auto-start your generator.
  • Let generator run for approximately a moment then re-connect to shore energy and our device will immediately shut-off your generator in more or less seconds that are 10-12. The green light on the MeanWell should come straight right back on.

ESSENTIAL NOTE: Turning the ALLOW CHANGE On or OFF will not impact the green light on the ShorePower track or MeanWell. Those two light will always be on IF the ShorePower Monitor is properly connect and you have shore power. The ENABLE CHANGE just allows or disables monitoring.

It’s this that a set-up that is typical appear to be when it is completed. You will see other consumer installation photos by clicking right right here.
