Will the suppressor from the pinto alternator work with a micra alternator? Pic attached. The micra one (top) has broken so was wondering if i could use the old rectangular pinto one. The numbers on the side don't mean a lot to me!

pinto and micra suppressors

Unless you are running a radio in the car, throw them away!
They are basically a capacitor which helps reduce radio waves, but can cause problems if the break down or short out.

Excellent, Thank you Nitram.

with out it my megasquirt wont work correctly

The 2.2 is the value of the capacitor, 2.2 micro farads, use away.....

2.2 is the capacitance value - 2.2 µF ( ooh look at me with my fancy greek symbols )

the other numbers would appear to be working voltage, 100 and 150 V.

as mitram says, you don't need it unless you have fancy electronic gubbins
