Buddy's car volt gauge kept going down so had battery tested it was good pulled alternator had tested it was good this wire that plugs in to the alt was broken so we fixed it put everything back in started right up volts gauge mileage was working put it in gear acted like it wanted to die without gas after we go home after two minute drive the volts gauge won't show anything and mileage is blank

I checked fuses to gauges on side of dash and under hood also switched starter and alternator relay and still same thing

Also when fired it and drove it for the quick 2 minute drive the volt gauge was at 13

I checked the plug that's goes to alternator with ignition on and plug in my hand it read 11.7v battery read 12.25v with key off I checked ignition relay #30 is at mid 8v should this be higher
