    Cat 226b thumb wheel switch replacement

    Hit it this morning again, both sides read about the same, the variations being proportional to the input signal so, running/stopped the voltages are different.m- this is probably why they went with PWM. Both sides measured ~4v @ center, ~1.88v up, 6.22v down. So, the issue doesnt seem to be...

    Cat 226b thumb wheel switch replacement

    I seem to remember the voltages being the same on both sides. If the LH shows closer to 1.6v/4v/6.4v v.s. RH 1.9v/4v/6.23v Then we can probably lean towards a bad switch. Interestingly, 1.9 is further off than 6.23v. Thank you again, I’ll get you that info tomorrow morning. Moving boulders by...

    I did. Was very clean, wires going to are great shape, no rust on the springs. Tried to get it to function by placing the rollers magnet on back-side of the sensor with no reaction, to that or a bigger magnet I could find. Tried to cleverly reverse the magnet, approach the sensor from the...

    Cat 226b thumb wheel switch replacement

    I dont know if this helps, but I’m working on a 308E2 that has a problem with this roller switch. I finally decided to take a crack at it again today. Problem: has thumb attachment, rolling forward, opens the claw, rolling down, nothing happens. No change in engine speed, no pressure in the...
