85. Ltd rec/reg

Morning folks, need some assistance. I purchased the 10-119H hot shot rec/reg from Ricks. Here is my question. The new one has 5 wires in the new bigger plug(2-red,1yellow &2 black), while the one I pulled off has 6 ( 1black,2green,1yellow &2 red). So now I am stumped and wondering if I bought the wrong rec/reg. This is on a 85 gl1200 LTD. Thanks for any help possible with where to look. I have searched on here but maybe I didn't word my question correct.

Been a while since I used an RR on my '85 Limited Edition, installed the external alt mod. The original RR should have 7 if not 8 wires: 2 red/white RR power wires, 2 green ground wires, 3 yellow stator wires, 1 black (sensing wire). The original RR has two connectors into the wiring harness. You will notice that there is only one red/white wire at the starter solenoid. This is because the two red/white wires from the RR are joined together into one wire just as these wires disappear into the bike wiring harness, the green (ground) wires are the same, two from the RR joined together into one wire in the bike wiring harness.

Had a look at the 10-119H RR wiring. Looks like it has 3 yellow, 2 red and 2 black wires from the RR into two connectors, one connector has red/black and yellow wires, the second connector has two yellow wires. The '85 Limited Edition has two connectors from the RR, the carb models have one connector. This is a pic of Rick's 10-119H RR:


Used this eBay web site for the pic: https://www.ebay.com/itm/RICKS-MOTORSPO ... 3296019929 Looked at a couple of other web sites and all have the same picture.

The black wire is the ground wire for the RR, the red wires are the positive output and sensing wires for the RR, the yellow wires are the stator wires. The two pin connector, yellow stator wires go into the 2 pin bike wiring harness, the larger connector connects to the 8 pin wiring harness connector. Make sure the red wire pin fits into the red wire pin of the bike wiring harness connector - there is two, pick one and make sure the second one is capped off however you want to do it as it will be live at all times and you don't want anything to touch it, the black wire (ground) fits into one of the green pins - disregard the second green wire connection, the third yellow stator wire connects into the yellow pin of the 8 pin connector.

Rick's RR uses the red wire as the sensing wire.

Good luck.

Man you are such a big help. So if I connect both plugs. New 8 prong to old 8 prong , the two red wires meet up, the 1 yellow does as well. The 2 black from the new plug match up to the 2 green ones and then there is a single black with green that is by itself. I have to cut the plugs because the harness plug is fried. What should I do with the lone black/green wire? You stated earlier that a red one is capped off.

From the diagram it looks like black/green goes to ignition fuse and starter switch. So should I connect it to one of the reds and then cap off the other red?

The issue you are working on is the RR, not the starter solenoid. The only wire on the starter solenoid that needs to be considered with the RR is the red/white wire. The black sense wire is part of the electrical system wiring and is powered on when the key is switched to the ON position, does not have anything to do with the starter solenoid, remove from the connector and tape/protect it from touching anything as it is a live wire when the key is switched to the "ON" position. The second green wire is a ground wire and do the same to it.

Do not connect the black wire to the second red wire in the bike wiring harness - not required/recommended, and may have the electrical system do some interesting things. Doing this would also keep power going from the battery into the electrical system after the key is turned to the OFF position. Think the system would not work as you would expect, and then you'd go down the proverbial rabbit hole trying to figure out what is wrong.

Definitely do not connect the green wire to anything, it is a ground wire.

Keep track of where you put the black and green wires. You may need a switched power wire for a relay - this black wire is a good candidate for this.

Can always use the green wire as a ground connection later for an additional component such as a USB port or such.

You can still order an RR connector set from Honda. Go into your local dealer and discuss this with a parts person.
