Re: 453 scope fan wiring help needed!


 

Phil
Lets see if this makes sense

There is a starter capacitor involved . 3 wire for the motor and 1 wire for the starter cap I think
the other starter cap wire is common to the motor

-DC

Hi all,

The fan on my scope was very noisy, so I pulled the back apart and got the fan apart from the shroud, only to find that the wiring is soldered in with no way to get the fan out to work on it.? So.... I cut the wires. Now, in the process of returning it to the scope, I've been reconnecting the wires, BUT in my clumsy style I managed to pull the shortest of the four (the black one) out of the back while attempting to strip it!? Grrrr.

So, now I can't tell where the wire connects to the scope!? I have three different schematics (manuals) and NONE of the three show a fan with FOUR wires!!!? Only three...... What the heck?!?

Is there anyone here who can shed some light on what I should do now?? That is... after I shoot myself!

Thanks in advance for anything you can suggest.

Phil
