I had Jake Brake problems on my 2002 Signature coach (ISM 500) similar to yours. It ended up being a bad foot-switch. Check the continuity between the two wires. It should be zero ohms when the switch is on.

I can see from the photo that your old setup was the same as my 2002 Signature was before I changed over to Lithium (LifePO4) batteries for my house battery bank. In my case I did not want to have the alternator charge the house batteries directly. I have a dc to dc charger coming from my chassis batteries to my house bank that can charge the house bank when the engine is running. In your case you want that option to combine both battery banks assuming both of your battery banks are lead acid types. The double buss bars on the bottom of the photo are for you house battery distribution to the circuits you want the house batteries to feed. It appears you have nothing feeding that bus. It needs to be fed directly by the house battery bank. In your case you want to have the option to combine the two banks. I believe all you need to do is identify the large red cable that is the direct feed from your house batteries and connect it to the double buss bar in the photo. (not to the input of the ML ACR) That will power the house. Then run another same sized red cable from the switchable output of ML ACR to the house bus bar. That should allow you to combine both banks when needed. However, I would not keep them combined all the time. You will need a way to charge the house batteries by themselves to their specific charge parameters when you are not plugged into shore power and unable to use your inverter/charger to charge the house bank. House batteries and chassis batteries have different charging needs. JJ

I recently installed the same alternator on my 2002 Signature. That alternator is self exciting -so it should have 14 .1 volts with engine running at the output when testing between the + and - on the back of the alternator - if the ground connection is good. You don’t even need to use a 12v sense wire or have the tachometer feed wire hooked up for it to work. It may need to have bump up in the rpm to get the self excitation to kick in. Otherwise it may be a defect.

Did you hook up the ground wire connection bolt on the alternator to a good common ground?

I recently replaced my DUVAC with the Delco on my 2002 Signature. No problems so far. If you go to my post, it addresses the issues you may be having. Good Luck, JJ

https://copilotgps.com It’s not free, but it works sooooo much better than RV trip wizard-RV gps map for your phone in my opinion.

Check for a reset button on the inverter.

Here's the Info I used on how to get the blink codes on my 2002 Signature ISM. Good Luck, JJ

My electrical manual is the same way-not complete and I don't have the fuse chart on the door. Once again thank you for the information. Now I have the info I need to identify what the fuses are for. Previously I had to waste a lot of time testing each fuse to find the bad one. JJ Paul, Thank you for the link to the 2002 Signature owners manual. I already have this and unfortunately, Monaco must have forgotten about listing the FR fuse list. Luckily I received photos of the fuse chart from Peter-(On The Road). So I am all set. Thanks to all that responded. I consider this post now closed. JJ

Thank you Peter-On The Road Again! You made my day. That’s what I was looking for. I’m curious about the name of the manual where this info is located. I have the 2002 electrical manual but it does not have the fuse diagrams you posted. I’m posting a picture of its cover and wondering if this is what your manual looks like? Thanks to the other members who replied. The 2002 signature front run bay layout seems to be quite a bit different. All The Best, JJ

Does anyone have a chart that shows what each fuse is for in the front run bay of a 2002 Monaco Signature? I need one… Thanks, JJ

Welcome! Do you have side cameras that work or just the backup camera? You need to determine if its the camera or its connection. If the side cameras work, then you need to check for a failed connection to the backup camera. Hopefully you will find it in the dash area. It could be as simple as it came unplugged. On my 2002 Signature, my backup camera did not work when I purchased it. I tried hooking up a new camera to the original cameras wire. It didn’t work either. I checked the camera connections in the dash-they were fine. I then started tracing the wire to the back camera. That’s the difficult part. Eventually I found a break in the wire and spliced it. Your other option is to buy a new wireless camera setup. That’s probably the best solution as the new cameras have much better resolution and are easy to install. Good Luck, JJ

Jim J, Thanks for all your thoughts. I want you to know that I got the Jake Brake working today. Thanks to you! I started my Jake Brakevtroubleshooting again today by double checking all the wiring. I checked the foot switch again and under the drivers side arm rest and found nothing out of order. I happened to read your post on my phone while working on the project. Based on your suggestion about the fuses on your coach, I checked every fuse in the Front Run Panel for the third time. However this time, I decided to use my volt meter to check both sides of the spade connector while having the ignition key turned on, to verify continuity through the fuse. Sure enough I found a 4amp fuse, #10 on panel # 2, not be conducting. It was a corrosion issue. I got my can of de-Ox it out and cleaned all thirty six blade fuses and fuse receptacles. Unfortunately I do not have a diagram of what each fuse does in the FRP, so I have to check each blade fuse when there is a suspected issue. That did the trick…Finally after another test drive, my 2002 Signature Jake Brake is back working great. It’s been a long time coming! Thanks again! I consider this post now closed. JJ
