Re: Battery alarm troubleshooting
"now the temperature light does not go on at all on ignition! "
That could just be a burned out bulb. Most idiot light systems are designed to self-test and light up when the key is turned. No light means the bulb has burned out, or there's a break in the wiring or other fault. But most commonly, a burned out bulb.
I'd suggest taking the bulb out and testing it, and if it has burned out, or if it simply was a PITA to access the bulbs, think about replacing them all while you are in there. Bulbs are cheap enough.
You may find different bulbs that will fit. If any are listed as an "instrumentation" bulb, that means they are usually a little dimmer but designed to be more robust, with a stronger filament that is less likely to burn out again. Filaments don't like vibration, engines will always offend them. (G) And these days, who knows, you may find LED replacements available as well.
