Are you not using the WIX filter look-up tool? http://www.wixfilters.com/Lookup/InterchangeMultiSearch.aspx?q=fl1a%7Cpf48&o=me If you dig around enough, you can find big filters. http://www.wixfilters.com/Lookup/PartDetails.aspx?Part=2011345

I guess I see what they are trying to accomplish, but it seems like a messy solution. And shame on them for the poor documentation. A little background information: Spinning alternators have a lot of stored electrical energy. When you key off, the energy dissipates through the battery. When you disconnect the battery from a spinning alternator, that energy still needs to dissipate. It dissipates backwards through your ground. It's called a load dump if you want to look up some more detailed information. The thing about load dumps is that it's a LOT of energy. Even on modern alternators like what are used on an LS motor, it can be 50V-100V for a couple hundred milliseconds. Try using those numbers in your resistor sizing calculations, and it seems irresponsible to call for a resistor. So how do you have your alternator wired into the system?
