Electric Power Steering-advice needed

1948 Ford 8N 12 volt neg ground. With loader.
After a considerable amount of experimenting I have an EPS unit installed on the tractor. Have the following problem. The battery is not a real expensive one, Walmart cheepo I think.Battery has full charge and has not failed once in two years.
1. Motor off, wired per instructions and power steering is great. Side to side with two fingers.
2. Start motor, still wired per instructions and nothing. It"s like before w/o the EPS.
3. Turn off the motor and I have EPS again.
Alternator problem?
4. unhook belt on alt. EPS works with motor off, but loses EPS once I start the motor.
5. Added the battery in my pick-up and the problem is the same.
Any suggestions would be great.

I'd say you have a wiring problem. Does it work with Key On Engine Off.

Probably the same reason a digital meter does not work around these old machines.
 
Key off-works great
Key on- engine off works great
It just seems like the motor is taking all the power from the battery and not leaving any for the EPS.
71 amp Delco-Remy alt charges 14+ volts at 900 RPM. Raising the RPM does not help.
Wiring has not been altered to accept this unit. Only change was to wire pos/neg for the EPS & controller.
Thanks, Tom/Idaho
 
Thanks to carlntexas it now works. I have a lot of time and a couple bucks working on this and I "might" have tried this before I gave up. It"s had solid steel/copper wires from it"s 6 volt days.
Carlntexas suggested I try old style carbon wires. I found some old used ones I had, tried them and now it works ALL the time. Digital multi-meter might even work now.
Can"t find any new carbon wires local. Can"t tell if the ones on this site are carbon or not. Anyone Know?

Thanks to all who offered their opinion and I really want to thank Carlntexas again.

lad you got it working and thanks for the update. I'm with TOH we need to see pictures of this electric steering.

Recommending solid copper wires will get you a guru patch tho...

In most cases the copper core wires would be recommended, but he needs non radio frequency interference (RFI) so the electric steering will work.
 

My point its a pure myth you need solid core wires but it will get you a guru patch... Repeat it a couple thousand times is all you have to do to get it...

It does prove one thing 6V is a borderline system it needs all the help it can get....
