Because its wuch a PIA to get to. I live on an island in Maine most of the winter the Generator is under the snow. If I can move it to the top or side I can service it myself. Iíve done this with automotive sensors who location made repair difficult. I suspect the location is to make repair a dealer job.
Cheers, Zaphod

Haven't you figured it out yet? The ultimate goal of design engineers is to make it as difficult as possible for service techs. So where does that leave us?

If there is already a mag pickup on the unit, see if there are any other holes it will fit in around the perimeter of the housing the existing sensor is mounted on. Sometimes there are alternate mounting locations or locations for backup sensors. I’m not sure if this applies to the little residential units though, I’m more familiar with the big diesels I get to play with at work.

I don’t think you should try drilling and tapping a new hole anywhere. I don’t see how you could do this in the field with sufficient precision. I’d recommend just leaving the sensor where it is if you are unable to find a preexisting alternate mounting location.

MPU sensors are added to larger units all the time with just a drill and tap but I can't remember if a 12RES has any good spot for it, but I do know it is no fun to change one.

Iím going to poke around the starter motor and look inside at the inspection plate. Hopefully I can drill, tap, or JB weld something in place. Iíll leave the old sensor where it is. Let you know. Cheers,

I cut away a bit of the flywheel shroud under the oil cooler and fitted anFord
Crankshaft sensor with the aid of a 1/2 in ID Delran plumbing fitting clamped to the cover plate. I shimmed it using a piece of he sensor box 048” works well. Cost $21.95
Woohoo!

I just wanted to post a update. I was having some trouble with the generator running the weekly test. I have Flight Systems control board in the transfer switch. They suggested some spikes are coming in on the pair of starting control wires. I twisted these together in a fairly tight twist and routed the pair in a way to stay away from the power lines. The generator now reliably runs its test and started and operated during a six hour power outage yesterday. But I have another strange issue, but I'll start a new thread for that.
