Canny lad Posted April 27, 2011 Share Posted April 27, 2011 My new one arrived today and it looks nothing like the old one so it must be a newer type... anyway as i am not exactly sure of the wiring what would happen if i wired it the wrong way?... its only got 2 pins on it so its 50 50 if i get it right or wrong Link to comment Share on other sites More sharing options...
barkwindjammer Posted April 27, 2011 Share Posted April 27, 2011 A rectifier is a series of diodes which allow current in one direction only-I dont think you can damage it, I'm sure an expert (Speedshop) will be along shortly to rectify this Link to comment Share on other sites More sharing options...

Moderator Airhead Posted April 27, 2011 Moderator Share Posted April 27, 2011 is there a diagram on it, like a triangle with a line across one of the points? Link to comment Share on other sites More sharing options...
Canny lad Posted April 27, 2011 Author Share Posted April 27, 2011 I lke a bit of AC DC talk in this forum right i see what you mean.. so basically it will work or it wont... and if it doesnt swap the wires around Link to comment Share on other sites More sharing options...
Canny lad Posted April 27, 2011 Author Share Posted April 27, 2011 is there a diagram on it, like a triangle with a line across one of the points? nothing at all mate just the code number and 300V on it... Link to comment Share on other sites More sharing options...
Moderator Airhead Posted April 27, 2011 Moderator Share Posted April 27, 2011 Are your wires red and white? isnt there male and female connectors on it that would prohibit getting it wrong? your wires, they have male and female connectors ...yes?

Canny lad Posted April 27, 2011 Author Share Posted April 27, 2011 the wires are red and white mate and the rectifier does have male and female connectors but the harness has bene butchered so i have no idea if the previous owner wired the rectifier up right or not as its hard wired into the harness...

I reckon the red goes to the male connector of the rectifier. Have you got a multimeter? Link to comment Share on other sites More sharing options...
Canny lad Posted April 27, 2011 Author Share Posted April 27, 2011 yeah i do have a multi meter... Link to comment Share on other sites More sharing options...
Moderator Airhead Posted April 27, 2011 Moderator Share Posted April 27, 2011 yeah i do have a multi meter... Switch it to 2k Ohms and plug the leads black in com and red in the ohms socket. Now test the two connectors on the rectifier, you will see a reading one way only...verify this Link to comment Share on other sites More sharing options...
Canny lad Posted April 27, 2011 Author Share Posted April 27, 2011 i got no reading at all using the Ohms... when i used the diode setting i got a reading one way but not the other Link to comment Share on other sites More sharing options...

Canny lad Posted April 27, 2011 Author Share Posted April 27, 2011 with red on the male connector i get a reading...with red on the female connector i get no reading Link to comment Share on other sites More sharing options...

Speedshop Posted April 28, 2011 Share Posted April 28, 2011 When you get no reading on the multi meter, note which terminal the red lead is on. Connect this terminal of the rectifer to the lead that runs to the positive terminal of the battery on the bike. Link to comment Share on other sites More sharing options...
JimR Posted April 28, 2011 Share Posted April 28, 2011 A rectifier is a series of diodes which allow current in one direction only-I dont think you can damage it, I'm sure an expert (Speedshop) will be along shortly to rectify this it well depends on the type of rectifier you are looking at... a good old 6 volt one is simple basically a zenier diode as the 70's evolved some of the 12v rectifiers also served the purpose of voltage regulation, which then added more diodes to the unit to turn the AC output from the generator to DC .. I.E cutting the wave form in half, then passing the resultant current to another diode which managed the supply to the battery (this diode went O/C if too much current was applied and stopped battery charging). 6V systems just tended to boil the battery (hence the phrase rectum fryer as most batteries were placed under the saddle), but later 6V systems added extra diode to make sure the battery did not boil Link to comment Share on other sites More sharing options...

That is a totally different set up and not relevent to this model. Link to comment Share on other sites More sharing options...
