    How many autometer gauges on a 3amp fuse?

    My autometer fuel gauge recommended an inline 3amp fuse for protection.  Can I run three autometer gauges on a single 3amp fuse?

    My plane is to use two 12 pin connectors to plug into the factory harness so I'll have the gauges split it half with each side getting its own connector.

    I would verify with Autometer.
    My replacement fuse panel came with a 5amp fuse for gauges.  I have the OEM, fuel, temp and oil pressure gauges connected to it, and I haven't had any issues.
    However, the Autometer gauges may require a different fuse rating.

    I'll reach out and ask them.   

    I'll be calling a good friend in Ohio tonight to discuss all my wiring with him.  He's very good at this stuff.

    The AAW fuse box in my car has a 5 amp fuse for the dash gauges which are all Autometer , my AFM and voltmeter re also on that circuit.
    My AAW kit is first generation , I see there have been two newer series.

    Remember the fuse protects the wire, not the gauge. Size the fuse according to wire size. Wire size is determined by load and wire length.

    The wires are small that came with the fuel gauge.   Maybe 20 or close to it.
