Trying to test a Yamaha remote oil reservoir pump ... RodBolt, anyone?

[nickfishbait]

I'm overhauling the oil injection system on my 1996 Yamaha 130 2 stroke.
I ordered a new oil pump assembly and trying to test it along with the old unit.
(This is the pump that is attached to the remote oil reservoir).
According to the article http://www.bassandwalleyeboats.com/output.cfm?id=942859 I should be able to put 12 volts directly to the pump motor to test it. No luck.
Here is what I did. I used a 12volt battery jumper pack with short wire leads and put the positive to the brown lead on the motor and negative to the blue (as the article states). When I do this, I dont hear/feel anything going on in the pump housing. When I move the negative lead around the motor feels as if it jumps for a quick second. I eliminated the possibility of corrosion inside the weatherprrof connectors by removing them on the old unit and testing directly to the wire - same results. Also the pump housing gets warm to the touch after a few minutes of "testing."

What am I doing wrong? I'd hate to find out the new and old motors are dead.

Thanks!
Nick

if the battery pack is known good and your jumpers are known good then the motor or wiring is bad.
12+ on the brown and negative to blue and the motor makes a humming noise if it and the above are good.

I tried 2 sets of jumpers and even used a car battery instead of the booster pack on 2 seperate motors (1used, 1 new) ... can it be that both are bad?
Is there another way of testing or checking out the parts?
If I take the cover off the end of the motor, is there anything that can be jumped in there?

Thanks for the help!
