At a minimum I will always take a multimeter with me when buying a starter generator and check continuity - if your get an Admiral MOT-2003 here’s the tests that I would check before leaving the supplier!

1st test -
(-)black lead grounded to housing (checked both end caps and middle section with paint removed)
(+) Red lead tested on each A1, A2, DF, F1 and F2 - my thinking was all terminals should have no continuity and read OL on meter
Results
A1: OL
A2: OL
DF: OL
F1: OL
F2: OL

If the F1 or F2 reading is incorrect, it indicates a possible grounded F1 or F2 terminal or a grounded field coil.
If the DF reading is incorrect, it indicates a possible grounded DF terminal or a grounded field coil.


Test 2
(-) black lead- A2 terminal
(+) red lead - A1 terminal
Results = 0.0 (cont)

Test 3
(-) black lead - F2 terminal
(+) red lead - F1 terminal
Results = .1 (cont)

Test 4
(-) black lead - F1 terminal
(+) red lead - DF terminal
Results = 5.5 ohms

Don’t accept the part unless your readings are good- if they have a power supply you can also have them show you it starts with power, you won’t be able to check the charging circuit without the voltage regulator but if your terminal readings are good you should be good to go when you install it back onto the cart
