The were the standard measure of automotive electrical current in all types of vehicles for the first 60 plus years the automobile existed! While all of the output of the generator or alternator passes thru the amp gauge on the way to recharge the battery or to deliver battery current to the electrical system, the same amount of current is also traveling around thru the rest of the wiring harness. As a result, there will be no change in the amount of current going into, or coming out of the battery, so the needle on the amp gauge in the dash will stay slightly above zero just as it was before the headlights were turned on.ДЄbsolutely they are safe. The additional electrical current needed to run the headlights will come from the alternator, not the physical battery. When you increase the electrical load such as turning on the headlights or heater blower motor, the alternator will automatically increase the output to cover the increased electrical load. An amp gauge will get less of a workout with an alternator, than it did with the original generator charging system. That tells you the alternator has already recharged the battery. Because an alternator charges at idle and low engine rpms you will see about 10 amps charging when you first start your vehicle then the needle will fall back to about a needle's width above zero in less than 30 seconds (most applications). It will work fine even with an alternator. if your antique vehicle came with an amp gauge, leave it in there. With mechanical gauges and non solid state electrical accessories, the electrical load in an antique vehicle can vary greatly. I want to know how much current is being used. So a volt meterВ makes sense for modern applications.Д«ut for the antique vehicles we drive and build, I still use and recommend using an amp gauge especially with a generator charging system. Alternators are built using solid state components which means less mechanical parts to wear and a more accurate charging system with better and more accurate control of the voltage output. The assumption is that if the voltage is between 13.8 and 14.2 (a 12 volt electrical system) that the battery is fully charged and the electrical system is working properly. So a volt meter simply measures the pressure or 'voltage' present in the electrical system. Only a small amount of current was used from the battery for starting which was quickly replaced by the charging system. As a result in was no longer necessary to measure the volume of current flowing into or out of the battery. It stored the current used for starting the engine, then the alternator took over and provided the current to run the electrical accessories and could replace the current in the battery in a matter of minutes.

That is why batteries last much longer today than they did in the generator days.ДЇor the first time a battery, became a storage battery. As charging systems became more reliable and were able to provide a constant output at idle and low rpms, the constant flow of current into and out of the battery was all but eliminated. It does not measure the volume of current (amps) being used. A volt meter simply measures the voltage or electrical pressure behind the current. Volt meters were introduced in the mid 1960's soon after alternators became common.
