Fitment FAQ
Will this part fit my specific model and year?
This voltage regulator rectifier is intended for Suzuki; GS500E; 1988–2000; GS500 / GS500K / GS500F; 2001–2009. It is best matched to original part number(s) 32800-33C01, 32800-30B01, 32800-33C00. Key physical/spec details from the product data include Voltage: 12V, Thickness: 28mm, Mounting Hole Distance: 66mm. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 32800-33C01, 32800-30B01, 32800-33C00 before purchase. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. This is especially important for Suzuki GS500/GS500E/GS500F/GSF400 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. If your original part number does not cross-reference with 32800-33C01, 32800-30B01, 32800-33C00, treat the fitment as unconfirmed. Model years outside 1988–2000, 2001–2009, 1991–1993, 1990–1991, 1996–2009 should be verified separately. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Confirm OEM/cross-reference number(s): 32800-33C01, 32800-30B01, 32800-33C00. Recheck listed specs such as Voltage: 12V, Thickness: 28mm, Mounting Hole Distance: 66mm. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
This Reg/Rec should work for any modern multi-cylinder bike. I have a 1993 FZR600 that recently was having charging issues. I found this because it's three-phase and had clearly distinguished wires. The connector with the 3 black wires are for the phase wires originating from the stator....if you don't have this connector, just chop em off and splice it into your harness or use normal spade male/female connectors to make the circuit complete.
The positive and negative wires are separate and clearly marked (red with blue line = pos, black with white line = neg). Again, if your bike doesn't use this connector, it's easy to make it work.
I checked the wires and function using a multimeter, and using the different biases (check out Youtube for how to test reg/recs), this checked out exactly how I expected.
Additionally, the potting feels of better quality on the back compared to some of the cheaper replacements, and the heatsink feels nice and heavy, like it will draw he excess heat away using the large fins. You can also mount these anywhere on the bike, and it includes an elongated hole on one side to make that easier.
Great product, and it's not permanently installed yet, but with jumper wires connected to my bike, I was getting 13.47 V at the battery indicating that it is working and charging the system.
