The conclusion: I need to install an auto idle-up to compensate for the electrical load drain during night time driving.

Howdy Dindo,

Unless your 240 is a door-to-door delivery van, this is not your problem. Even if your idle RPM is too low normal drive cycles will spin the alternator fast enough for long enough to provide full charge.

If the battery voltage continually falls during normal operation, one of two things is happening. Either the load is excessive or the charge rate is inadequate. It is that simple. I, like Ken C, tend to suspect the alternator side of this equation.

The only way to know for sure which is the case is to measure the battery input and output currents. Post the results the shop recorded.

Off topic -- What did you do about your carburetor problems?
