Tazio Posted March 11, 2015 Share Posted March 11, 2015 Can anyone confirm the correct wiring for a VX starter motor?I have a brown wire from the start relay which I think is connected to one of the spade connectors on the solenoid ( does it matter which one?). On the screw on stud I have the output of the alternator, a red power lead and two brown leads. Is this correct?., the reason I ask is I don't know the serviceability of the starter, I have 12v to the brown lead that connects to the solenoid when I push the start button, but the solenoid doesn't respond....

Member Jonathan Kay Posted March 11, 2015 Member Share Posted March 11, 2015 Can you get a model number of the starter or a photo of the terminals?Check the solenoid and starter and engine earths.Jonathan Link to comment Share on other sites More sharing options...
Tazio Posted March 11, 2015 Author Share Posted March 11, 2015 Engine is earthed via the off side engine mount. The starter is the standard Bosch one for a VX. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 11, 2015 Member Share Posted March 11, 2015 If the solenoid doesn't do anything noticeable when it gets 12V feed (measured at its terminal, not the other end of any wire) then either its earth isn't made or it's knackered.It's probably worth disconnecting, cleaning and reconnecting both ends of the earth cable .Jonathan Link to comment Share on other sites More sharing options...
Tazio Posted March 11, 2015 Author Share Posted March 11, 2015 Yes but assumes the wiring is correct. As this is the first time I have tried to spin the engine since it replaced a k series, I need someone with a VX to confirm the wiring is correct.

Member Jonathan Kay Posted March 11, 2015 Member Share Posted March 11, 2015 That was the next question... about when it last worked.It would help a lot to see some photos or a sketch with wire colours of how it's currently (!) connected.Jonathan Link to comment Share on other sites More sharing options...
Mavic82 Posted March 11, 2015 Share Posted March 11, 2015 Alan,forget your our wiring for a moment and try a fly lead directly from the positive battery terminal to the solenoid. A quick strike will determine whether it works, and tell you which terminal you need.actually often best done out of the car with a spare battery.then as long as your switched live works ok all should be good. The main terminal is a convenient connection point for significant positive connections. It is not due the starter particularly they join here.

F355GTS Posted March 11, 2015 Share Posted March 11, 2015 AlanAs Mavic suggests take a feed from the battery live and touch the spade connector it shoud cause the solenoid to fire and as the piston pulls back it joins the connector with your alternator/ battery wires to the one going into the starter (internally) forcing the starter to turn. The signal wire to the spade (or smaller 6mm stud if it has that is normally White/Red or White/ Brown Link to comment Share on other sites More sharing options...
Tazio Posted March 12, 2015 Author Share Posted March 12, 2015 Cheers guys, something to try tomorrow. Link to comment Share on other sites More sharing options...
Tazio Posted March 13, 2015 Author Share Posted March 13, 2015 Just an update, removed the starter, put 12volts across it, it spins up, so looks ok, but found a poor crimp on one of the connecting wires, fixed that so onwards and upwards. Link to comment Share on other sites More sharing options...
