so theres no way to get just the gas gauge to work for now?

 

Does everything else on your display work I should ask I guess?

If not...
can you soder a motherboard? you need a low heat iron and you can buy the power supply for $20 and soder it yourself. Otherwise just buy the remanufactured motherboard that has the new power supply sodered in for you.
The reason the guage doesn't work is because the mb's powersupply is shot, it happens all the time with our digital displays. check my post above for info on what/where to search in ebay, search"blazer mb"$57 shipped and your display with work 100%.
