Placement of diode

I have 2 8ns converted to 12v. I have the diode soldered in the wire off the alt. Been thinking of a better way since I don't want to accidentally break it while working on the tractor. Thinking of going this route. Diode would be safe and I could use the other side of the switch as a backup safety to the ignitionew or whatever. Any thoughts or better idea.

I installed a bulb socket with a 5 amp (4.9) amber bulb (194, I think) as an alternative to the diode. It serves the same purpose plus gives me a visual indication of the alternator charging.
 
With the diode across the terminals, it won't do anything unless you "disconnect" the switch each time. If you have to do that, why have a diode?
 
i like the conversion kit I bought from YT a one wire alternator simple to install works good, alternator supports four headlights and two flashing amber lights when plowing snow at night.
 
just solder it in the wire and slide a piece of heat shrink over it or a piece of small hose. No need to make life difficult.
 
(since I don't want to accidentally break it while working on the tractor.)Where is the cover for it to protect the diode?
That idea is kind of like heading straight East from Los Vegas to get to Los Angeles.
 
Like JMOR said if you put a piece of heat shrink tubing over the diode and shrink it down it will provide some protection and prevent it from shorting out anywhere.
 
If it works as well as mine did, u can keep it in your shirt pocket wrapped in tissue paper so it will be well protected--
 
Running alternators, converting to 12v and modifying wiring takes away from being original. With that said why not consider running a charging indicator lamp on the dash, that can eliminate the need of a diode and also provide you with an indication of a functioning alternator. Nothing wrong with a diode but the lamp serves two purposes instead of one.

Another option is, you can also run a diode across the terminals of the bulb that way if the bulb burns out the alternator can still charge.

I don't use a volt meter or amp gauge and use that hole for a temp gauge . When I flip the switch on and the light is bright I have a good idea the battery is fully charged . When I start it and the light goes out I know the charging system is working , just like they have for years .It is not something that is a day to day issue . The best part about the big red light is reminding me I left the switch ON which happens way more often that an electrical issue . Usually the gauge just tells me there was a problem now deal with it .
 
(quoted from post at 00:55:18 02/07/17) I use plugs that have the diode made into the wire.

Unplug your plain plug from the alternator, plug in the new diode plug into the alternator, then plug the original plug into the new one.
 
I just recently finished converting my 48 8N to 12 volts. It's the best thing I've ever done to my tractor !!

I was planning to install a light on the dashboard, but I didn't have a suitable light so I used a diode I had on hand as a temporary option:

The blue wire is long because I left enough to reach up to the dash where the light would be mounted.

As you can see I just used crimp connectors on the diode.

It works so well, that adding the light to the dashboard is probably one of those jobs I will never get around to doing... :)
