Just wanted to share with the group the results of a recent electrical problem I had. Over the Labor Day holiday, I lost the right stop and turn lamps on my Jayco TT. Running lights were ok. Troubleshot the fuses and wiring and concluded it was the Power Distribution Center. Did some research and being an old Avionics troop, thought I would order the relays and change them out myself. Found a source for the relays, ordered them and then they went on International B/O. So, I got a little nervous and sourced a new PDC from Moparpartsonline.com. $431 plus shipping and no core charge. Bit the bullet and ordered it. Ten days later the new PDC showed up AND so did the B/O relays. When I ordered the PDC from Moparpartsonline, I provided my VIN and the new PDC arrived with all the fuses and relays in place. Don't know if that is special or not but pretty sweet. The first thing I did was swap out Fuses 47 and 48 from 15A to 10A fuses. Yesterday I decided to tackle the job anticipating it to be an all afternoon project. The six big connectors took a small learning curve to figure out but by the time I got to the three by the battery, it went smooth. I did break a locking tab on the small electrical connector (green) in the middle between the big six locking ones. Not sure what I am going to do about that yet. In any case, everything works as advertised including all my trailer lights. I took the old PDC into my shop and it took me all of 20 minutes to figure out how to break it down to the circuit card within. I am going to desolder and replace the relays with the new ones. I'll let you all know how that goes...
 
Do a detailed visual inspection for bad tracks I would think that track failure is more likely than relay failure.
 
I will do that. Initial visual inspection did not reveal anything out of the ordinary other than two of the three relays had some slight bubbling or swelling of the case. The third that sits by itself in this three relay cluster did not exhibit the bubbling or swelling.
 
I just realized I put this in the engine and transmission forum. I meant it for the non engine and transmission one. If anybody has the ability to move it, please do and sorry for the inconvenience!
