Not quite as beefy as the Stancor/ Allied/ white Rodgers but I think its a much better unit than the Napa, Int, Ford units.
Story is, I bought a 4 post under hood solenoid for my fisher mm last year. It was very well made and heavy, much heavier than the one that was installed in the truck when I bought it and I paid $25 retail for it. After researching I see that the majority of the OE and aftermarket solenoids are all 12v continuous and 100amp except for the Stancor / white Rodgers / Allied that everyone seems to like.
I went back to the place I bought the under hood solenoid for my plow last year and got it to try out as a replacement GPR. I went to the web site Trombetta Motion Technologies
and found the link to the PDF on their Continuous Duty PowerSeal http://www.trombetta.com/cm/pdfs/TRP...t-pwr-seal.pdf
. It is a totally sealed unit specifically made for high amperage - The one I picked up is a 684-1221-012. It's a flat bracket the 5th number of the part number indicates that (you can see that if your viewing the PDF) it didn’t state the amperage so I called Trombetta and was connected with a gentleman that told me it was good for 150amps.
You can also get them in 15 volts, he told me it takes 9 volts to trigger it so there shouldn’t be a problem. You can also order them in different bracket configurations, you can see on the PDF that if you follow the numbers I posted it's basically a code for each spec of the solenoid or solenoid you need. So a 684-1541-012 would be a PowerSeal (6) non grounded (8) standard powerseal (4) coil voltage (15) bracket type (4) bracket location (1) duty cycle (0) Contact material (1) sealing (2)
So here is a 12 or 15 volt/150 amp continuous, completely sealed, heavy duty well made solenoid that is available in different bracket configurations (which really shouldn’t be an issue, it takes 10 mins to make a custom bracket to adapt to the existing one for your particular mounting location) that retails for $25 or so.... you cant order them from Trombetta, but distributors sell them in cases of 36 so maybe we can get them cheaper if enough people come together to order a case or more from one of their listed distributors.
I found them online when I searched the part number also - I installed it today in my truck. Just another option I wanted to pass on to everyone.
