 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.
