Sorry lifter01 but you are wrong. SC3000 has Zapi contollers, SC4000 has master/slave GE Gen II SX units (not an EV100 panel as per SP), SC4500 (A/C) has Access units as does SC5x00. SC4000, SC4500 and SC5x00 all have distribution boards.
No Access in the OP's truck so no dash menu. Apparently no BDI/hour meter display working hence my post about no power from the GE controller.
