Unlabeled Fuses
« on: April 07, 2021, 05:13:06 pm »
I've been acquainting myself with the electrical system of our 2008 PC2350. Keelhauler's 2552 Electrical Schematic has been a great help. Even though my PC has the older Trip Lite Inverter/Charger and the IOTA distribution panel, I've found that his schematic still matches my unit's wiring pretty closely.

My question involves the 12V fuse panel. From Keelhauler's schematic and from a number of other posts that I've searched on the forum, it appears that PC typically uses only fuses 1 through 8. On my coach, fuses 1 through 8 are labeled and match Keelhauler's schematic. Fuses 9 through 12 are also used but are not labeled. It appears to be a factory install as all 4 wires go into the factory wire bundles behind the distribution panel.

Does anyone else have a unit that uses fuses 9 through 12 and do you know what they supply?

Wow Randy, as owner of a 2019 2552 with an entirely different converter/power panel unit I will be of very little help except-----

while you're waiting for feedback from someone with a compatible unit, use the old trick of pulling each of the four fuses one at a time and carefully review what (if anything) goes dead.  From your description the fuses certainly look functional, so each one should kill one or more "somethings" when pulled.

OK, I realize it's been over a year since I did this post, but I finally found the answer. I was in the process of replacing my failed Tripp-Lite Inverter Charge with a Renogy unit and was enlarging the hole where the remote panel mounts for the larger Renogy remote panel. This is next to the Iota distribution panel. In the process I noticed a taped-up bundle of 4 wires coming from the back of the Iota panel and leading nowhere. I realized they were the unused pigtails leading to fuses 9 thru 12. I had assumed because they had fuses in them, they must power something. I have removed the fuses and put them with my spares.
