Boost Switch Solenoid

Would this be the proper solenoid to replace my boost solenoid?

P38226 is the Part# MOT had for the one they put in my coach. According to this 2001 U270 parts manual , it's a 4 post, 100amp/12v continuous duty solenoid with with part# 77-90000-100. MOT charged me $68 for mine. Different generation of coach though so proceed with caution.

Yes that is the one. I just changed mine and it's the 200 amp one you want.

 The Cole-Hersee 24213 200 amp continuous duty or a solid state equivalent is the correct solenoid for the ignition or boost solenoid. 100 amps won't have a long lifespan. Amazon has them for $55 plus tax delivered. https://www.amazon.com/Cole-Hersee-24213-Continuous-Solenoid/dp/B005K2429I

What I noticed when changing mine is to save money Cole-Hersee made the posts a
little shorter so I couldn't put all the wires back on the new one so I had to work around
that.

How are you diagnosing a bad booster switch/solenoid?
