I am measuring with the engine at full throttle with battery connected at the B+ on the regulator. I dont see how it would drop the 4v throw the wire to the switch and battery. Im to the point of wanting to buy another regulator but i kind of like the diag part to figure out why so please more helpful information
Ok, you have 18volts at the regulator output. Do you have 18volts at the battery. If the battery is reading a normal value of 12.5-14volts then there is a bad connection between the regulator and battery. As I said above, a battery should not read 18volts. If it does it is defective or being charged by a huge current, which is not the case here.
You have to make sure you have a good connection between the regulator and + battery and also between the engine chassis and the battery - terminal.
At this point I would disconnect the battery and use an ohm meter to check the connections. When the key is on, you should have a low resistance between the regulator output and the terminal for the + side of the battery. You should also see a low resistance from the metal regulator case to the - battery terminal.
The regulator could be faulty but your voltage readings are not making sense. You need to do a little more troubleshooting to find the actual problem. Let us know what you find.

Any chance that your losing the ground on the regulator case ? But being you changed the regulator this is just a shot in the dark . Al
That is a possibility. The connection needs to be there from the module case back to the battery-. With a rubber mounted engine there has to be a separate wire back to the battery. The regulator will not work without this connection. Sometimes it's easy to take the chassis connection for granted and that is a mistake as it is just as important as the + side. I hope he gets it sorted out.

If your testing it with the wire connected it sounds like you found your problem , bad crimp , broken wire or bad connection I would think .
How does it drop so many volts through the wire?
