Looking for some technical advice on Lionel PA-1's.  I have the D&H PA-1's 6-14574 (6-14576 Dummy).

The fan motor that spins the cooling fan (roof) has stopped operating.  When I last operated these units about a year ago everything was still functioning prior to my placing them back in their box. 

After the usual touch up on lube earlier this week I ran them, but did not notice that the trailing unit fan was not spinning.  I noticed today.  I looked for anything unusual and found nothing.

Here is what I have done:

1) Tested the leads to the motor - good.

2) Tested the motor with a used 9V battery (7.5V) - the motor operated.

3) Checked all board connections - everything was clean and tight.

4) Nothing smelled like burnt electronics.

Am I most likely looking at the fan motor regulator PCB?

Any help would be appreciated.

Thank You in advance.
