On February 10, 2018, I purchased a ProMariner Combi 2500 QS from Pat Elliott while attending the Ranger Rendezvous at Burnt Store Marina. I installed the unit with all new batteries on my 2010 Ranger Tug, Shearwater, a few days after the Rendezvous. Pat Elliott said he had it repaired by ProMariner as a replacement for the original unit that came with his Ranger. He assured me it was an unused “working spare” that was nearly new. I paid $300.

It worked flawlessly for the first 10 minutes of initial testing.

When I next turned the inverter on a few days later, it sounded a continuous alarm and produced no power.

According to the installation instructions and the ProMariner service department, the sound meant either an internal inverter error or a high or low battery voltage. ProMariner asked that I disconnect the 120 Volt lines and connect the inverter to a known good battery. I ran the requested test; the DC voltage indicated about 12.8 (new battery, just off charge) and the buzzer continued to sound.

I returned the unit to ProMariner for repairs with an RMA from their service department.

Testing revealed the unit had been “modified internally” and could not be repaired. ProMariner also said the unit was “several years out of warranty.” I replaced the unit for $565 with an exchange offer from ProMariner. ProMariner said they would refund the replacement cost if I provided proof of purchase showing the unit was within the two-year warranty period.

The new replacement was delivered yesterday and is installed and operating normally.

I had several discussions with Pat Elliott requesting he either provide me or ProMariner with the paperwork indicating the unit was less than two years old or contact ProMariner and provide the requested proof to them directly. He would neither provide ProMariner or me with the requested proof of purchase.

Pat Elliott offered to refund my $300 if I delivered the defective unit to him at Burnt Store Marina. Since the unit was, at that time, at ProMariner, I suggested he contact them directly to arrange to have the defective unit shipped to him. If the unit were shipped to me, my shipping costs would have exceeded the $300 in dispute.

I also provided the RMA and the ProMariner contact information to Pat Elliott.

The conversation ended abruptly when Pat Elliott yelled for me to “shut up.”

There seems no way to compel Pat Elliott to return part or all of the $300 I paid for what turned out to be an older, internally modified, and soon to be defective inverter.

What, if anything, should I have done differently.
 
I tend to not purchase used electronic equipment for that very reason. I am surprised at your experience with Pat. He has always seemed to be an honorable person. It also seems odd that the unit was modified internally. Most of the unit has circuit boards and capacitors. I'm not sure what someone would do to modify the unit and why they would modify it. Based on the trade in price and the price you paid you aren't too far off from the cost of a new one. I guess lick your wounds and chalk it up as a life lesson.
