Hi everyone
I have rebuilt mainly landrovers over the last 20yrs so this is a new thing for me although I am a qualified electrician.
I have purchased a mini that was converted over 30yrs ago, the motor runs ok powered buy 4 batteries.
Its as far as I can make out the motor is a series motor and has four wires two going to armature (A1 & A2) and two going to coil (S1 & S2).
I have a curtis controller with contactors mounted on a nice big alloy plate.
All connected up and runs at variable speed well however I cannot seem to get the motor to reverse.
I would love some advice as I have tried just about everything now to get this motor to reverse.

To reverse electrically, the polarity of the armature and field windings need to be reversed; this is normally done by a contactor arrangement. Think of a four-way lighting switch...

have you got any pics of the install? Is this one of the BMC converted minis or was it done by a private individual?

Hi
Thanks for replies
See attached it was completed by a local chap to me as a project many years ago and has just sat in a garage/barn until now.
It was setup as on or off. So I have fitted a Curtis controller set up on a Noco board.
Motor runs just struggling with the reverse bit. The Noco/curtis is set up however cannot get it to reverse not sure if wiring is right as motor has no details plate or markings.
I don`t have much experience with motors so its a big learning curve.

Just re tested and finally worked out the wiring which is a real relief and the motor now runs forward and reverse at variable speed not just on/off.
now just need to see if the transfer box works ok.
