How do i fit a honda 250 rectifier to a suzuki gsx550e

possibly the rectifier faulty or stator coil

Yes. you may need to make some engine mounts to fit the new engine to the old frame, but you will also need to transfer the electrical harness from the RM to the TS chassis.

start looking for a full harness fo replace it with thats just a mess and will only lead to problems down the road

As suggested, check the voltage with the engine running accross the battery. If its below 14 volts you have an issue with the stator windings/regulator/rectifier/wiring.
Do the cheapest thing first and clean up all electrical connections, esp the earths.
A manual will tell you how to test the charging system, but the Suzuki GS range has always had charging issues.
The simplist method is to fit the combined reg/rectifier unit from a Honda CB250/400 Superdream.
Always keep your engine oil topped to the max mark, as this cools the stator.
Dont leave this, it is not unknown for the entire system to fail including the CDI if left unchecked.

It will technically fit, but it will not mount right. Chaz Moto DC
