There's a nice writeup on satelliteguys of trials and tribulations of actuator sensors.
I purchased a 36" super-crap actuator just over a year ago and now wish I would have just spent the cash for a Von Weise.
Since having this dandy of an actuator I've added a pinion gear to support the main drive gear and keep it from flopping around and take up slop.
Discarded the reed sensor and replaced with a modified hall sensor board. Again from a Saginaw motor.
Made a magnet trigger wheel with 20 small neodymium discs with alternating N-S poles to drive the hall device hard-off.
The original magnet trigger/reed showed 5 short and one long pulse per revolution on an oscilloscope. That and motor slop was generating accumulated count errors when sweeping through the arc and back. Added more count errors when searching for and peaking signal on new sats.
Even a 20 year old Saginaw motor with a rusted out motor has a robust gear train with little gear slop.
I really wished I'd have spent the extra on the Von Weise.
Now I guess I will.

Just to update everyone today after many days of playing about with this actuator arm i called in a sparky to have a look at it and he got his multi meter on the wires and the 4 core cable was indeed perfectly fine , the Vbox [ Amiko ] was sticking quite a bit but not the problem either i had everything wired up okay motor wires were reading slightly above 36 volt but the sensor wires nothing zero not even milliamps , tested the limit switch adjusted upper,lower CAM but still E-2 ERROR ON Vbox and nothing was hitting any limits ..so that narrowed everything down to the reed sensor itself ....son of a b*tch !!

i took off a few reed sensor switches from 2 of my old arms that were laying dead in my shed and we connected it up turned on power to VBOX and Bang counter started moving no more E-2 Messages as i yelled at the top of my voice in relief... a tiny little part with 2 wires [ reed sensor switch ] was what stopped everything... and ...exactly what everyone was saying all along

The arm was sent out with a faulty not working reed sensor switch

now both my 2 meter and 1.2 meter dishes are moving free and fast ... although my signals now on my 2 meter dish are very slightly lower than normal which tells me i have to make adjustments and peak my signals better a small job for my trusty 14 mill spanners , my tape measure shows i fitted arm at 5 and a half inches and it should be just 5 inches to track every sat correctly ...a minor adjust which was my fault when installing the arm but i am getting the whole area around my poles for both dishes cemented in the next day or two so i will be checking my pole is still plum and level and aligning everything even better very shortly ...i will take a few photos once i get this big job done and all should be looking really well Brand new Arm and new cable and even now i decided to use my brand new Vbox
so for next 10 years + i should be trouble free with any kinda luck at all : )

Thanks to all that gave me the great advice on getting this issue resolved u guys are great !!
cheers !

Nice one Barney , glad you were able to get it sorted & it was a relatively simple fix. The reed switches on these actuators can be a pain in the a$$ at times, I've had to change mine a few times & was able to source a couple of bare (not encapsulated) ones from Ebay. One problem they have is that the leads from them are just pushed through a grip to make contact on the small PCB, after time the pressure on the grip can fail leading to more E2 faults I don't know if it's the same on a 36" but I soldered mine in & no more faults since. (maybe make this a sticky--Actuator Faults & Fixes)


Regards
