Jubilee Wiring Diagram - Is this correct?

Thanks,

• My Wiring Diagram

It would be better if you wired the AMmmeter in the place of the Pushbutton (your diagram) and wire the Pushbutten (hot side) to a NEW Junction Common to the REG & Ignition & Ammeter (HOT). The other connection from the Push-button to the Starter should not connect to anything else.(The Selonoid you are using is not Standard as it requres voltage)

You can think of voltage like a plumber and starting from the battery/Starter it should go through the ammeter and then to a common Junction which supplies voltage to all the Loads.

Your Lights are now wired directly to the battery and that load will not show on the Ammeter

You could leave your Push button direct to the battery but make sure nothing else is connected to the selonoid side (except the selonoid).

In my schematic I THINK the small 'double rectangle' device that the ammeter runs to is a terminal block. The right side (in my drawing...the bigger rectangle) has got to be the hot side since the keyed/switched circuit to the coil runs off this side. This confuses me though since it appears my alternator leads go to the voltage regulator and then the hot lead from the regulator runs to this 'hot side' of the presumed terminal block. It is not clear how the alternator output gets back to the battery!...I guess I'll re-examine the wiring. There must be something I messed up in sketching it out!!??

I've seen a 6-to-12V conversion schematic for the late 8N's. It has the Starter button wired in series on the ground side of the starter ciruit. I guess I could do this as well. My tractor doesn't use the original starter button. It has a new starter button installed on the right side of the cover (in the tin above the battery on the right).

I definitely need to work this out. I feel I'm going to re-wire my entire tractor!

FYI, my ammeter and headlights are not functional. I assumed they are old and inoperative. Perhaps it is faulty wiring?

Paul.

The most confusing part is the apparent use of NON-Typical alternator with external voltage regulator. Most successfull 12v conversions use the Delco 10SI with built-in voltage regulator.

Most of the time, the old 6v squarecan voltage regulator it cut-out and thrown away. But some converters leave them in as convient wire-tie points. That works for the original converter, but is difficult for follow-on trouble shooting as you're doing.

The use of non-standard starting motor solenoid and non-safety starting button on the dash is also counter-productive to remote troubleshooting on the internet. It might be intuitively obvious for someone with an eyeball inspection ability, but even with yer drawing, I can't do it..... ...respectfully, Dell, a 12v advocate for the right reasons

Yeah, I'm scratching my head on this one too! I haven't gotten back to the tractor to investigate further. But, I have come up with a modified version of my wiring diagram which is linked below.

It assumes that I can find the ground from the starter and place the starter button on series on the ground side of the starter. I would use the small terminal block with one side "always hot" and the other as "key-on hot".

However, since I haven't gone back and gotten details on some of the parts I need to find out:

1) Details of how the solenoid is wired up. Right now there are some small guage wiring in the original diagram.

2) Perhaps the starter button needs to go from the ground side of the solenoid? Again, I need to investigate.

3) Some folks add a diode in the system to prevent a trickle down circuit. Where would I place this? Is it necessary?

4) I have to determine the type and brand of the alternator. Or, I could change over to the Delco 10si. I am wondering if this alternator is an older Ford type?

Take a look at the 'Proposed Wiring Diagram' which is based on modifying my existing set-up.
