I mis-spoke. The 2 bolts for the voltage regulator only need to be taken out if you need to relocate the regulator. If you do, take out the bolts, move the regulator around to the back side of the bulkhead that it is botled to and use zip ties to secure it.cire said:Is it something that can be built or am I better off purchasing one? Thanks Stoutner PS the zip ties I see must be the bottle heater...
