Re: Battery alarm troubleshooting
jb, go to WallyWorld or Target and spend $20 on a digital multimeter. Put it on the 20VDC setting and test your actual voltage, engine on/off.
That's the only way you'll find out if the problem is in the alarm, or your battery/alternator are dying. Unless you want to just wait to see what dies.
