MC54 250 Charging Issues

[srphatness]

So my battery isn't charging.
About a week ago I tightened down the loose ground connection and it started charging again (I would get 13V at the battery when revving the engine).
Now it's not charging again I took the plastic off and have tested the coil, which appears to be fine i get about 1.5 ohm between each wire. and the regulator seems to be OK because I read about 13-13.5V on both sides of the connector. But why is the 13V charge not getting to the battery anymore?
Looking at the wiring diagram it appears that the only thing between the connector (that works) and the battery is a 30 amp fuse. So that is going to be my next suspect.
Is the fuse the round metal thing that sits right next to the battery with two large red wires bolted on it, and two small wires coming out of it?? and if it is bad can I open it to get the fuse out, or do I have to scrap the whole thing?
Thanks for your help guys.

No that is the SOLENOID(RELAY) that transfers the Voltage to your starter when you press the start button.

The Regulator/Rectifier is the one that charges your battery nothing else. I assume you have a volt meter since you checked the coi. Check the battery and see what volts it reads, it should be at least 12.5. sitting there without the motor running. It could be the ground connections broke or got loose so check them again.

So I found something interesting out. When I start up the scooter it is charging, or that is to say I get a little over 13V at the battery. Until the fan kicks on. Once the fan comes on I only get about 12.2V at the battery. Seems like the fan is sucking down some serious juice. Could this be my problem???

Thanks wile. With a full charge the battery sits at about 12.4V I would have to pull it out and charge it again (It's about 3 months old)

yep once the fan comes the voltage continually falls. Not good. I wonder if I don't need to replace my fan. How many amps should the fan draw???

The grounds are good. Thanks Wile
How many volts should I be reading off of the regulator??? I wonder if it just isn't providing enough juice for the fan to run?
Thanks again guys
