Anyone know what the ARC fuse is for in the fuse panel of a 91 z-28? mine keeps blown car want run at times and id like to track it down plse hlp my ole 200600 mile car .

 

ever figure this out? mine isn't blowing but it's pulling a constant draw on the battery when the key is off...

 

The ARC fuse goes to the radio ( the wire that keeps your radio memory). GL with it hope you firgure it out . Im sad to say im no longer a Camaro owner bout me a 98 grand prix gtp ( supercharged ) :P

 

does anyone have any idea how much this ARC fuse circuit should drain. i'm assuming since it is a constant that technically it should light up a test light in theory it's always going if it's constant right?

as far as the grand prix that's nice, i have one myself with some extras. good luck with it too as i have had more recals and things go wrong with that car then any of my other cars.



but it's still fun to drive.

 

You should never have more than 500 milliamp current draw on any circuit. On a standard test light (12v, 12ohm) 1 amp should light it fully. If you can see a dark orange filament thats dimly lit you should be OK.

On a newer car with several electronic control modules 400-500 milliamp would be acceptable (some Ford products normally draw a little over 500 milliamp). However vehicles like ours with little to no electronic memory should be under 250 milliamps. My car draws only around 100 FYI.

 

yeah it lights fully and the light goes out when i remove the fuse. what should i do then? i've never tested this before so i don't know if i've always had this problem or not.
