Default Motor terminals a1 a2 s1 s2 on a series 48v ds

Hi

I'm trying to diagnose an intermittent no go condition on my 2001 ds. Can anyone explain the terminals on the motor and how they work in conjunction with the f/r switch (lever type)?
A1: B+
A2
S1 ?
S2 ?

I figure these terminals have a specific purpose for reversing polarity, but it would be great if anyone could share more info on their function.

Thanks

Google is your friend on this subject.

The motor can be trouble shot by testing for unwanted continuity (short) between the armature (A1 & A2) and the field (S1 & S2).
Use a simple continuity test with your DVM. you should have continuity between A1 & A2 and again between S1 & S2 but not between any A and any S terminal.
If the motor continuity test are good move on to testing other components.

wow! im pretty sure the OP wasn't looking for a dissertation on motor theory...


anywho, the switch reverses the flow of current to either the armature or the field. the block diagrams below show the reversal of current flow through the field.

How would YOU know? It seems the only reason YOU are here is to badger the help. Step off, or step out.

Some other motor terminals called F1 & F2 besides A1 and A2. What's the different between S and F terminals?
TIA

Typically, Shunt wound motors have terminals a1, a2, f1, f2 and Series wound motors have a1, a2, s1 and s2 . . . if that is bad info, someone will clear it up . . .

My motor has the A1, A2, S1 and S2 setup. I assume 2 are forward and 2 are reverse? But which is which?

Wrong assumption. Current has to flow through both the armature (A) and field (S or F) to generate torque. Reversing the flow in one or the other will reverse the direction of rotation.
