These are all Bosch 14V voltage regulators that are compatible with Bosch alternators.
If you have a Marchal or Motorola (or other brand) alternator, these will not (may not) work for you.
All showed nearly identical voltage readings at the battery when installed in my car.
#1 Bosch 0 190 601 009, Germany. In very good condition except black electrical tape has replaced the factory yellow tape which fell off. Also the mounting holes are larger, so a small washer is needed behind the two mounting screws.
#2 Bosch 0 190 601 006, Germany. In very good condition.
#3 Bosch 0 190 600 046, Brasil. In new condition. SOLD SOLD to Fran
#4 Bosch 0 192 062 007, Spain. In new condition. Looks like a newer solid state design as the can is smaller. SOLD SOLD to Mark
Inexpensively priced so you can have a spare for your car.
All asking prices include shipping to the lower48.
#1 - $20 All are pending SOLD
#2, 3 and 4 - $25 at this point
Late Merry Christmas and Happy New Year.
