Choosing the correct rectifier regulator for your Suzuki
From 1977-1986, Suzuki used a mix of three different rectifier/regulator models for their street bikes, primarily the GS-models. Although the rectifier/regulators themselves were essentially the same across all models, they featured three different lead-off styles. Rick’s Motorsport Electrics carries direct plug-in replacements for all three. Please use this guide to determine which rectifier/regulator will properly fit your motorcycle:
If your OE rectifier/regulator …you need part number:
is terminated with… 
10-202
Three AC input wires with male bullet
terminals, a DC positive with a female bullet
terminal, and a 6mm eyelet on the ground wire
Three AC input wires and the DC positive
going to a 4-position female connector and
the ground ending in a female bullet terminal
Five male spade terminals embedded on 10-222
the rectifier/regulator itself with no lead wires
On the 10-202 and 10-212, the white/red, white/blue, and yellow wires are the AC inputs, red is DC positive, and black/white is DC negative (ground). For the 10-222, use the pin-out provided on the chart.
NOTE: We carry heavy-duty versions on some of the 10-202 (10-221H) and 10-212 (10-223H) applications. It is highly advised that these be used instead of the stock OE replacements.
