Grinding at my brain 🧠

I really want to get that starting battery voltage meter working reliably before my summer vacation next week. It sounds stupid, but I like having an accurate number associated with the starting batteries’ voltage just so I can feel safe leaving the truck parked for multiple days. I know it’s unlikely the dual-AGM battery SuperDuty with a gasser engine is likely to have issues starting by ordinary parking during the summer months, but like a oil pressure or temperature gauge, it’s good for reassurance. I have two voltage gauges on the way, plus a box of RC Snubbers and the hope is this will get me a good reliable gauge – maybe not for this weekend – but at least for vacation.
