I recently installed 4 hide-aways strobes and a Whelen SPS 660 power supply in a 2004 Cadillac Deville hearse for a local funeral home. The install went well and all the components work without problem.

The only question they have is the electronic fuel gauge is now acting up. I believe it was tweaked when we disconnected the battery to change the sidepost terminal. Is there a reset for these computers. It has a half tank of fuel, but it drops to low fuel and then back to 1/2 tank. Any help would be appreciated. Thanks.
