Goldwing 1200 rectifier when it gets hot

Postby fastf » Mon Jun 18, 2012 2:47 pm



This is a picture of the rectifier that came off of my 1200 LTD two years ago .It went out with no warning left me on the side of the road at night.When I pulled it off there was a piece of solder touching the frame that came from the curcuit board that had melted and was touching the frame it was a wonder it didn't fry my electrics.How I found out it started smoking when was replacing the radator hoses and had the bike running the black glue was melting and running down behind the rectifier and down on the top of the motor.

Further proof that electricity is compressed smoke. :D
Wal Mart sells a digital display meter with a plug on it for $17 in the auto section that I put on all my bikes.It's surface mount and works well.

The 1200 LTD has a digital display volt meter I hadn't had the bike a week and did not know much about the bike then.But believe me I do now there isn't much you can tell me about a 1200 LTD I haven't done or replaced in the two years of owning this bike.Once I got everything right shes a very good bike.

I showed this picture to let people to check the rectifier too it ain't always the stator and and the three yellow wire pull the rectifier out and look on the back just to see if is getting so hot to make it crack.I wish Honda could have placed it under the bottom of the fairing and made a small scoop to catch air to help keep it cool where it sits there is not much air getting to it.Also you people that have just bought a 1200 LTD and SEi and it is not charging don't listen to the first person you talk to in these forums and he says stator on these bikes the stator is alot heavier than the standard 1200 because of the fuel injection and such get with people that actually own these bikes they have a boat load of knowledge and can can help you and alot of these people might live in your area and will offer to help you too.

Don't summarily dismiss the knowledge of other type of bike owners.

My advise is based on common Gold Wing knowledge and a electronics background,and should be taken in that context.

The stator in the fuel injected model is capable of providing more current,but the inherent problems still are there regardless of what bike or design you may have.
Corrosion is the number one killer of the electrical systems.
Corrosion/oxidation leads to resistance in the connection,this leads to concentrated heat ,arcing,and a loss of current.
I'll lay odds that if you really analyzed every crimped wire,switch and plug on your 30 year old bike,you'd find quite a few.

When I say to SOLDER the 3 yellow stator wires,it's for a reason.It's so badly oxidized that it no longer will preform at peak efficiency.

As always,there is a procedure step by step process to diagnose ANY charging system,and on the 80-87,the first most common starting point is the stator plug being melted.

Nicely put if you read I was replacing the radiator hoses and had the false tank off .The stator wires the electrical tape was actually melting and comming off .I cut the plug and hard wired it cleaned the groung and also all the connections and dielectric greased them too.For a bike that had sat out under a open shed for two years the connectors were in good shape.What I have seen in forums is people giving advise to people from people that don't have a clue what they are talking about they read or heard from a friend that is the problem.I highly advise you what year Goldwing and what cc you ride to ask them for advise.I too have some electronic back ground and also owed and restored cars and several motorcycles most of my life I do know how to turn a wrench and when I'm stumped I go to these forums and get with people that own these bikes like mine because most of them have crossed the bridge as far as problems as mine the thing I like about these tech forms you get to meet people and help people too.

As a rule of thumb,when I need info about a problem,I read a copious amount from different info sources then take the most common answers as confirmed fact and the oddball details as questionable.

I do the same as you alot of my knowledge is years of trail and error and scratching the bald spot on the back of my hard head.
