How to wire up a 36V EZ-GO motor for testing

[cbm25]

I have a 36V motor pulled from a 1979 EZ-GO Marathon. I am a college engineering student trying to use the motor to build an electric motorcycle. I need to test the motor to ensure it still functions. The motor itself has four terminals- does anyone know specifically what each terminal corresponds to? and subsequently how I should wire it up for this application? I have browsed through the forum and have seen many people point to the following link:

However, I don't know which terminals on my motor correspond to A1, A2, S1, & S2. If anyone has any insights it would be greatly appreciated!

My motor is the same as this one:

assuming that is a series motor...
2 posts connect to the brushes/armature (A1, A2)
2 posts connect to the field coil (S1, S2)

8V to 12V should be sufficient for testing

Every early motor case is stamped Look closer or scrape some dirt off of it.... It should be: ( but no guarantee and absolutely no liability assumed)
0=A1
1=S2
2=A2
3=S1
You must verify this by finding one or more markings on the motor before applying power.

These motors are unsupported at the drive end. you will need to make a plate that can carry a bearing for this. Electrically, do everything " scottyb " says! In my IMHO, a cart motor is not what you need for your application! It is heavy and needs a ton of juice to run it! There is no room on a bike to put the batteries that are necessary!
I'd be looking at starter motors for vehicles. Although these are made for intermittent duty, I have seen them used for a lot of different applications and hold up just fine. They also take a smaller battery capacity.
Good Luck on your project, it sounds Cool! :)
