This vehicle won't have an amp gauge but might have a volt meter. A battery should have about 13 to 14.5 volts present when the engine is running and the alternator is working properly. Fair warning: the gauges are notoriously inaccurate so the best way to check the charging system is at the battery terminals using a simple good old fashioned hand held voltmeter. A fully charged battery, with the engine off, has 12.6 volts. If you have only that amount of voltage or less with the engine running then you have a charging system issue.
