Be advised..if your rectifiers inside the alternator are bad (shorted) this product will NOT fix it!!
All this thing will do is take some of the load from the internal diodes (providing the resistances are equal or less).
When diodes are set in a parallel configuration, all sorts of problems crop up....and you end up with an unstable bridge sort of setup.
Best to replace the internals with new ones...and possibly get higher rated ones at the same time.
