Cruising Equipments Amp Hour

Cruising Equipment introduced their first battery Ampere-hour meter two years ago. It rapidly became everyone's first choice for system instrumentation. Well, the fine fellows at Cruising haven't been idle. They have invented a new model Ampere-hour meter with radically better features, more intelligence, and it measures two systems at once A battery Ampere-hour meter keeps a net count on current flow into and out of the battery. It is a meter that tells us how much electric energy has been...

Figure 6 shows the POWER CONVERTER circuitry in detail. I used a 1 2 Amp fuse although a smaller fuse 1 4 Amp should also work fine. The fuse was placed in a Radio Shack 270-1211 inline fuse holder. An On-Off switch after the fuse could be added also. Four op-amps are used, with 3 being in one LM324 package U3 and the 4th in another LM324 package U4 . Do not attempt to combine these op-amps any other way as their power pins are hooked-up differently U3 uses 12 and GND, U4 uses 5 and -8 . Be...
