Problematic - Performance Parts and Accessories

I'm clearly not the only one complaining about this. I bought mine a few years ago and had problems with it from the start. Well, it ended up failing completely. I bought this to use with Derale 16825 (https://www.amazon.com/gp/product/B004XONXRQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1#customerReviews) which I rated 5 stars a few months ago . , also mentioning problems with the relay/controller. It was unreliable from the start, intermittent operation over the years caused the engine to overheat twice and it didn't work well with the personals display, but it was the only game in town to stall at Derale. I will say that Derale had good customer service (at that time at least) but didn't comment on any issues other than saying they would send a new one, but I just think it's the design and/or production this thing could be better . HOWEVER I'm ordering a new one now as I already have everything I need to easily replace it. I cannot recommend any other brand as few of them are made in a 70 AMP version. Big fans. UPDATE: A few days later. Have to reconsider my compliments to CS. I think things have gotten a little worse in 10 years. I decided to fix the thing before ordering a new one. Well, the call to CS didn't do much. I didn't want to damage anything so I asked how to access the circuit board inside as I couldn't find any hidden screws. I was told there were no screws and that the entire block was sealed with putty that could not be removed. When I asked if this was a planned obsolescence to force another purchase at a high price the answer was NO as any moisture getting on the circuit board would ruin the unit. When I mentioned that there were 4 external holes covered only by collapsing lugs that obviously allowed moisture to enter the unit for years, I was CLOSED. Before I hung up the guy told me that any attempt to enter the hull would destroy the block immediately and it wasn't worth trying. If it still doesn't work, why not try. I carefully removed (using a high speed hacksaw with a thin round blade) the circuit board which is attached to a block of rubber plastic material. If moisture is what they were concerned about, a gasket could do that and allow for a repair. Anyway, I went in and was able to just solder the broken yellow wire back to the board and voila - WORKING AGAIN. A real pain, but I saved over $120 and enjoyed it. I'll post an update if/when the thing stops working due to age or my bravery to open it up for repair. I would like to point out that the 2 control wires for this unit are really flimsy and VERY SHORT just to cause problems. Just having more strands and another 3 or 4 inches would make the installation much more reliable and easier. I've replaced the yellow and green wires with longer and heavier ones and I don't think this will be a problem anymore. I'm curious to see how long the rest of the PCB components last. I still love the fans I connected to it so find out.

Pros
