Older Lister  Petter Charging Equipment.  Dynamo, Alternator, Control Box.

For the majority of Lister engines  in the 1960s and 1970s, the way the engine turns (engine rotation) is the first thing you need to know.

Most series were available as either clockwise or anti-clock rotation. The rotation is defined by which way the flywheel turns when running, as viewed from the flywheel end of the  engine.

For starter motor fitment the engine rotation  always determines the motor to be used, but when it comes to dynamos or alternators the position on the engine

and which shaft the drive is taken from all affect the appropriate equipment rotation. For alternators, the difference is down to the fan fitted; they will charge in either direction.

For dynamos it seems to be a debated issue whether they will produce charge if run in the non-design rotation.

In any event, remember that  a new dynamo needs to be 'flashed' before it will produce current.

To polarise for a negative earth installation,  connect the battery negative terminal to the dynamo body and then, using a wire connected to the

battery positive terminal  brush the other end against the 'F' terminal  on the dynamo a couple of times.

For a positive earth system, the above connections are reversed.

Another potential source of confusion with charging equipment can arise with the issue of whether they are LH or RH. Pretty much all Lister and Petter

up to the 1980s used dynamos or alternators with two separate mounting lugs, in line and a single lug for belt adjustment. The photo below illustrates LH and RH.

If you are uncertain about the rotation of your Lister, then for all flywheel fan cooled (air cooled) versions please have a look at our starter motor page for a quick guide.
