FLtractor 157 #1 Posted 5 hours ago (edited) Afternoon, Based on 856 wiring diagram .. the middle voltage regulator wire.. to make sure I read the diagram correctly … the middle voltage regulator wire… goes to the positive battery terminal then the positive battery terminal goes to the B on ignition.. is this correct way or do I wire the voltage regulator middle wire directly to ignition Battery terminal?

It doesn’t take a lot of rust to seriously impede the flow of those poor little electrons trying to do their job! Share this post Link to post Share on other sites
pfrederi 20,213 #4 Posted 4 hours ago My answer above assumes this is an original 4 terminal regulator. You really should clean the terminal and make sure it says BAT not GEN...On 3 wire regulators the center terminal is GEN and goes to the A terminal on the genny. 2 Share this post Link to post Share on other sites

Some light 220 grit sand paper the terminal to clean up the rust? Share this post Link to post Share on other sites

Where would the words BAT and Gen be.. on the circled pieces? when you say center terminal GEN.. where is the A terminal on generator that that connects to?

pfrederi 20,213 #9 Posted 2 hours ago (edited) The marks are stamped into the regulator terminal. Wire brush? As rusty as the one is it may have corroded the stamping away. Is yours a 3 or 4 terminal regulator (the 4th terminal is on the bottom if it is a 4 term and a light wire runs from it to the A terminal on the Generator body Heavy 4/6 ga wire Battery + terminal to the Ignition switch. There are two terminals on the generator body and there is a stampd letter next to them an A which has two wires one light one heavy and and F one wire from the F terminal on the regulator Edited 2 hours ago by pfrederi 1 Share this post Link to post Share on other sites

There are normally only two wires here I assume the new red one is for the fuel pump you are installing and is not the new red one in the regulator picture that would be wrong.

All of that makes heat. The only one that looks like it might be ok ok is the main red wire with the yellow connector. Share this post Link to post Share on other sites

The old red wire is coil to I on ignition. new wire is fuel pump to I on ignition. Old black wire is to the jewel generator Warning 856 dash- to the I on ignition.

If the bare rusty terminal cleans up to show "L" Then you have a 4 terminal system. AGAIN... is there a terminal and wire coming out the bottom of your regulator???? When i say light I mean light gauge wire... Where does the new red wire with yellow crimp terminate on your regulator go. Look I am getting old an I try to use a variety of wire colors makes tracing things much easier.... not all red Edited 1 hour ago by pfrederi Share this post Link to post Share on other sites

Look I am getting old an I try to use a variety of wire colors makes tracing things much easier.... not all red Don’t see any L… the new red wire with yellow on middle voltage regulator.. goes from there to battery + on battery itself .. then the battery wire to the B on ignition. there is this wire underneath my voltage regulator.. see picture.. which I think goes to the starter gen nut terminal on top of the starter .as seen in my 2nd picture here .: .. does that mean it’s a 4 terminal? If so.. what exactly do all the terminals .. 3 on front where red middle wire do and are for exactly? Edited 42 minutes ago by FLtractor Share this post Link to post Share on other sites
