Can you post a picture of your alternator - front/back/side?

ernest
the model is 14684N

i cut one of the ears of the alternator as suggested somewhere,
i am working on a "side support" that will mange the alternator not too "twist" on itself when he will be charging.
the lower bolt is a 3/8 grade 5 bolt.

on the rear connector of the alternator there is no letter at all,,so it would indicate which one is which !

after i will check for a V strap at the hardware store.

Standard three wire setup is used. Recommend using 8 gauge wire for the alt output to the system. You should be able to buy rubber boots to protect the output connection from CDN Tire. The three prong outlet at the back is:


Minimum hookup is the sense wire and the IG terminal. The indicator lamp is nice to have, I have mine located in the dash plastic just below the digital dash and off to the left. The indicator lamp came in handy when I was on a road trip to LA last fall. Light came on in Redding CA before I got too far down the road, replaced the alternator at the local Honda shop and back on the road in 24 hours. It gives an instant response to alt failure and you notice lights sooner than a gauge. 16 gauge wire is good for these connections.

Looking good.

well
i have finished fixing the alternator in place,not the cables yet but i decided too redone the cooling system:the fan circuit.
i dont like at all the way the fan is fixed there,way too near the belt,the crank pulley,,
i decided too take it of and fixed another fan ,smaller .

i will let you know how it is going on,
i scrapped my 4 blades fan because of my error,if you see one let me know ok

thanks

i just need the 4 plastics blades

many are sugesting :power steering pump pulley from the old Honda Prelude years but i dont know much.

for i ask to a friend that was agile with a mills and he "turned" mine using the shematic available,
after there was some mods to the pulley but it worked perfectly.

do you have a machinist around you? thats the way to go.

Can anyone help me, I made my own poor boy kit it's all installed and fits nice but my problem I hear of everyone getting good volt readings like 13.6 at a idle I have a hard time getting that at 3100 rpm it's like I have to ride in lower gears to bring up my rpm in order for my volt meter to show its charging. I'm getting 13.3 volts at 3500 rpm, 13.5 at 4000 rpm. I have my 8 gauge wire comming from the main power post of the alternator going to the battery with a 50 amp fuse 5 inches from the battery. Then off the IG post on the alternator I'm running 14 gauge and plugging it in were I unplugged the voltage regulator. The only wire that gets juice with the ignition turned on I think it's a black wire with a red stripe if I recall. My alternator is a new Chevy mini street rod race 70 amp 3 wire. I don't understand this I'm hooked up the same way everyone else is but I have to have 3100 rpm in order to charge. Any help would be greatly appreciated the warm weather is here.

Interesting scenario - something is not hooked up properly. I have the alt conversion on my '85 LTD. The main wire to the battery is fine. The three wires on the back of the alternator are for sense, excite and a lamp. Here is a picture of it:


If this is not what you have, need a picture of the alt where the posts are. Good luck.

what are the diameter of your pulleys?

where did you connect the SENSE wire of the alternator,?

mine is an home made kit,
i add to OPEN the main cable harness to have a GOOD connection at the rights places,you should connect on the starter relay ,,

check on goldwingdocs.com for photos ,,many persons have modify their GW ,,i sent some pictures myself.

Thanks for posting the pics. Checked the owner of the thread, be better if you started a new one so we can be specific about your issue. Will review your issue regarding the wiring.

Gervais, I like you had a very hard time finding a pulley, car quest said they could order me one for 168 dollars and would take several weeks so I ended up ordering one from the UK it's only a 2 inch pulley. I hooked my yellow wire witch is ignition into a wire that I unplugged from the voltage regulator it's a black wire with a red stripe and it's the only one that activates with the ignition, are you saying to wire my main positive to the starter relay instead of the + battery

on mine it is a 4 inch on the crank and 2 inch or 2.25 on the lternator

That's another thing that has me baffled I have a 2 inch pulley and 2 1/2 on the alternator that 2 inch pulley should be turning that alternator much faster than a 3 or 4 inch pulley. For now I have that external voltage wire connected to my positive battery post

well
"I have a 2 inch pulley and 2 1/2 on the alternator that 2 inch pulley should be turning that alternator much faster than a 3 or 4 inch pulley"

you have a ratio of 1 to 1
i have a ratio of 1 turn of crank for 2 turn of alternator,

if i add the place i would have fit a 4.5 inch ,
the motorcycle engine dont revs as automobile engine and just check on your car the alternator and your crank car pulley.

Also the sense is VERY important too

So do you think my problem is my crank pulley is to small? Where did you connect your sence wire?

yes,absolutely.
your alternator cannot reach his max output because it is too slow.
mine is a 55 amp and enough,,

i must go now,
when you fit the 4 inch crank pulley you will have to take the radiator,the lower part,further by 3/4 inch because the fan will touch the alternator strap.check my picture.

i have found some picture of my open harness too .

Just wondering if you have had the alternator checked out? Sometimes new stuff is bad right off the bat.

Hondas no I haven't had the alternator checked. I guess I should do that I'm about out of options. Thanks for the help
