carluk69 Posted August 26, 2013 Share Posted August 26, 2013 Hi there Ive tried looking through the archives come close but to no avail so my apologies if this is like a re post i own ( reluctantly recently ) an xj400diversion 1991 she just keeps popping bulb checked the voltage and its just under 18.0v time to fit a new voltage regulator this is the problem the one that's fitted is the wrong one has their is a extra wire hanging out of it and there is only one bolt holding it in and no plug its been cut and tapped together what im wanting to know is how to wire a plug up to the harness to fit the new regulator Ive added a few pics any help would be appreciated thanks Carl http://i1251.photobucket.com/albums/hh552/carluk69/T.jpg http://i1251.photobucket.com/albums/hh552/carluk69/Photo2016.jpg http://i1251.photobucket.com/albums/hh552/carluk69/Photo2013-1.jpg Link to comment Share on other sites More sharing options...

Moderator drewpy Posted August 26, 2013 Moderator Share Posted August 26, 2013 its not a voltage regulator its a rectifier in your pictures, which is it? Link to comment Share on other sites More sharing options...
NE0 Posted August 26, 2013 Share Posted August 26, 2013 its not a voltage regulator its a rectifier in your pictures, which is it? It might be one of those combined regulator/rectifiers, similar to the one i used on the DT175MX 12v conversion. One side is the reg the other side is the rectifier. Edit:- yeah, just looked on ebay.....loads of them available listed as regulator/rectifier Link to comment Share on other sites More sharing options...

One side is the reg the other side is the rectifier. then it shouldn't just have 4 wires then, because reg/recs have 7 wires. Link to comment Share on other sites More sharing options...
NE0 Posted August 26, 2013 Share Posted August 26, 2013 Take a look at my DT175 12v conversion post, where i used a Honda Cub regulator/rectifier. I disconnected the rectifier and used the combined one to replace both. Not all have 7 wires. take a look at post 21 The original 6v DT rectifier is only 2 wires and the regulator is only 1 wire (earthed through the casing) A minimal combined unit would have 4 connections (one being the earth) Link to comment Share on other sites More sharing options...

Edit:- yeah, just looked on ebay.....loads of them available listed as regulator/rectifier thats why im a bit confused it is an combined regulator/rectifier thats come off being the wrong one becouse they fitted this one to the later version so ive orderd the correct one for the earlier version but just need a bit of guidence withe the wiring has ive no plug on the harness to conect it when it arrives if you understand my meaning thanks Carl PS sorry for posting in the wrong section (longday) Link to comment Share on other sites More sharing options...

Totally different engine set up that's why I never mentioned it as the thread gets confusing then Link to comment Share on other sites More sharing options...
Moderator drewpy Posted August 26, 2013 Moderator Share Posted August 26, 2013 looking at an old loom on ebay it looks like ABC is white wires from stator D is red to battery with an earth to body, granted its off a 600 model http://www.ebay.co.uk/itm/1995-YAMAHA-XJ600-XJ-DIVERSION-WIRING-LOOM-HARNESS-BREAKING-PARTS-SPARES-/290959957705?pt=UK_Motorcycle_Parts_13&hash=item43be909ec9 Link to comment Share on other sites More sharing options...

Speedshop Posted August 27, 2013 Share Posted August 27, 2013 OK as mentioned the one marked 'the right regulator' is not suitable for your application - its for mopeds. Looks like someone has fitted a Superdream regulator to your bike. This is a popular mod as the Superdream regulator is a solid reliable unit. With these things the mounts and type of regulator are important - not what bike it fits - if the wires are different - its easy to change. Looks like you need a 3 phase permanent maget type (not field controlled like the Honda CB550 or XS650) You can use a 5 wire unit or a 6 wire, the extra wire is a voltage sense, Yamaha like to use this type of regulator (the CB250 wetdream uses the same type) The sense wire must be connect to the main circuit after the ignition switch. If you tie it to the red you might find if works well but after a few days the battery will be flat as the regulator circuit will be 'leaky' and the battery can drain through it. Thats why the brown wire is used as its is switched off with the ignition off. Link to comment Share on other sites More sharing options...

Speedshop Posted August 28, 2013 Share Posted August 28, 2013 If your bike has a 2 phase regulator that'll work, if not it won't. But at 21 quid it'll have a computer powersupply voltage regulator in it (rated at 10 amps max) - good luck with that Link to comment Share on other sites More sharing options...
carluk69 Posted September 1, 2013 Author Share Posted September 1, 2013 Thanks to all fitted and working will report back in the coming months see how long the cheepo reg/rec lasts Link to comment Share on other sites More sharing options...
