T25XHD - Our Second Best AD Series Alternator Bridge Rectifier. For the Highest rated rectifier see part # DR4402HD3
IMPORTANT UPDATE: This rectifier not longer has 2 copper heat sinks, only the positive diode plate is copper the negative is aluminum. Also the battery stud is not copper as there were breakage problems with copper if you were not careful, plus it is no longer silver soldered into the diode plate.
Extreme Heavy Duty Bridge Rectifier For Delco AD237 and AD244 Series Alternators
Note: This Heavy Duty Bridge Rectifier may be installed in lower amperage units such as the 105 amp AD237 which will make it super heavy duty. To use this later design rectifier with an early design voltage regulator, all you need to do is run a jumper wire from the battery post on the Rectifier to the power input spade connector on the voltage regulator.
