2003 750 Magna. Why are voltage regulator wires and the plug in they go to getting very hot?

SOURCE: Alternator or Voltage regulator

if you can carefully put a metal wrench on the rotating pulley of the alternator and felt a magnetism attracting the metal wrench, then your alternator is charging. if there is no magnetism, then the alternator is not charging...

another test is to measure the voltage on the small wires that went in to the alternator that says "F" for field, it should measure battery voltage...that is the voltage from the regulator..that means your regulator is working...but the altrntor is not..

without that battery voltage, then the regulator is he culprit...



pls be carefull...

hope i was able to solve ur problem..

pls rate me.. tnx, drcool..

SOURCE: no power from transformer

I had the same thing happen on my original Roady2. I suspect the powerplug port on the Roady2 unit is not getting a good connection. Does the transformer plug have a plastic tip? You can try to cut that off with a sharp razor blade. Sometimes that will make a good tight connection. What I did was buy a used Roady2 unit on ebay. Also another cause is


the power connection is not being made by an internal problem or wear caused by constantly plugging and unplugging the power port. I use a Cambridge XM playdock boombox at home. I bet getting a different unit will solve the problem. The only problem is that finding a used unit might take some work. Good Luck

Replace Fuel Filter.
Test fuel pump output.
Remove and service carburetors.

1.What?

2.What?
You charged the battery off of the battery charger with a trickle charge. The battery wouldn't charge while you're riding, because your alternator took a [email protected]
(Sorry if I seem gruff, but I'm an old biker, and Harleys are all I ride. I'm also a Harley mechanic.
Shhhh! I don't want that to get around! lol!)

3.Battery is at 13.4 volts now? What is the specific gravity of the acid in each cell? Don't have a hydrometer? Do you have a load tester? No? Since you measured the voltage, do you have a multimeter?

Test the voltage with the bike running. It should be around 14.6 volts when charging, less with the battery fully charged.
Don't get the correct reading, then you better look at alternator replacement. (Regulator is built in)

SOURCE: wire connector between stator & voltage reg/rectifier burnt

your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot
