Well maybe a couple of them, but I am just trying to get a grasp of the electronics of my scooter. My first question is, the Rectifier charges the battery while the scooter is running, correct? And are the Rectifier and Regulator the same thing? Secondly, are there different "Strengths" of recitifiers? Meaning, does one type of rectifier charge the battery faster, stronger, better, etc..? Now, my main question, and I only ask this because I saw a post from tvnacman about there being different 4-pin rectifiers, how do I know which rectifier to purchase? It seems that people are having a terrible time finding good ones.

a rectifier is simply an array of diodes connected in opposing ways to convert ac voltage to dc voltage. strength would mean the size of the diodes ( ho much current it can handle) amperes. a Regulator keeps the voltage constant regardless of how many rpm's the motor is spinning The source for the voltage is the stator.As far as the pin configuration goes, it depends on your harness.It charges the battery yes. In some cases, it also powers lights etc. Most are both regulator/rectifier.

DX DC voltage looks like this ------------- AC voltage looks like this ~~~~~~~ The R/R is a bridge configured series of diodes.. Diodes only allow current to pass through them on one direction...therefore any voltage that falls below that imaginary line on AC voltage...is dumped to ground. Hence the name 1/2 wave rectifier. Many of the large Scoots with lots of lighting and accessories use a more complex and costly Full Wave rectifier. It is actually 2 rectifiers in one..able to use voltage above and below the invisible datum line....because each one has a different polarity. If they made a more powerful R/R it would not help anything because the stator only puts out about .5 Amps or less. You can make one with a higher voltage output...but anything over 15v going into a 12v battery will cook that battery. As for different 4 pin R/R..it refers to the pinout and how the wires go into the R/R. They all do exactly them same thing...it is just that some Scoots are wired differently. Bear with me and get others to clarify if needed...I am not an electronics Engineer...that was my father. I am merely a retired USMC Combat medic..retired with 21 years service. Now a Cardiac Tech with a Nursing degree. Reason I went that route with my career.... Well like this...I got tired of the Old Man forcing Ohms law and other stuff on me hoping I would follow his footsteps. Did he not realize when Teens... we do the OPPOSITE of what you force..and preach?...lol...

Firstly, I would like to say thank you to carasdad for your service for our country. That is quite a career you have going there. While most of your response sounds like a foreign language to me, some of it I do understand. The real reason for my asking was to find out if I purchase said rectifier, should I be looking for something bigger and better than what I currently have installed. I have been having some battery issues in the past and wanted to know if there was a reason that the battery wasn't charging like it should. I think I have narrowed that problem down to a faulty positive battery cable. But while I had my scooter apart, I was looking at things I could improve. I think your response has helped me. So thank you.
