Key wires.

108

T-tap into it?

Nothing exposed on the key switch itself I can easily get to

109

Yes, tap into the switched wire. Blue is maybe not big enough.
Wires are smaller on one side of plug I guess.

Still not sure of what you mean. There is an unused starter position #3 spring loaded.
#2 position is on.

111

Hello, still there? …

112

This is what I was thinking. It sounds like he may have lost the “home” position (being off).

Find the position you remove the key?
Then how many clicks forward to ON?
From Home(OFF) does it also go back one click to ACC?

113

I think acc is pos 1.
In any case only one pos is used. #2

114

Yes,

-OFF
-ACC (also ON)
-Spring loaded dumb position (doesn’t do anything) I mean it keeps it ON

115

Think I’ll call it a night. We can pick it up tomorrow if you get the relay connected to the key switch.

Or check the continuity with the multimeter on the key side.
Flip the key and it should “Beep”

117

I’m here… sorry… just trying to make sure I’m doing what we’re thinking. Trying to figure out the switched side between red and orange

This what you had in mind?

I’ll alligator clip to blue.

Also, now that blue is disconnected from the bus bar, the display powers up normally. No solenoid cycling and rebooting.

Yes, tap is switch from key and stays on with key?
I see you found a yellow. I didn’t want to wait for Amazon again. :slight_smile:

119

See if the switched 12v stays on now.

Bought a whole kit :wink:

It’s on and nothing wonky. Should I drop the parking brake and see if it will move?

121

Look for solid green on Sevcon. Then yes .
If it faults notice when.

122

Fyi, Sevcon all need to start in neutral.
Pb and other safety switches are not connected.

123

Sevcon isn’t awake. Do I need to complete the circuit with the orange side of the grey wire and hook that up elsewhere. When I go blue to orange with multimeter, it’s hunting

124

Not following. You left everything the same except connected the blue to switch?
Gray wire?

125

Yes… Orange on the center post. Blue disconnected from the busbar and alligator clipped to the key tap.

If I take a volt reading from blue to orange with the key on, shouldn’t I get 12 volts?

126

Yes, orange is minus 12v? Then to blue is 12v.
