I know the Qs have been answered, but having a VS built by Kirk I figured I would chime in:
your questions:
1- Is the low gas light supposed to work and at what point? To my knowledge VS cars with the Chinese repo gages were not wired with a low fuel light. I collected as much documentation +wiring diagrams as I could get my hands on from kirk between 2013–2016 and the standard senders he used did not offer this capability.
on the topic of fuel gauge needle bounce; to reduce/ eliminate you can install one of these behind your gauge - plug and play (https://www.stoddard.com/nla20100100.html). There was also a member in this forum that made/ sold their version of the linked resistor gizmo- improved- for a better price years ago… maybe they have a spare laying around. @Gordon Nichols
2- My trip odometer is stuck at zero. Any advice on how to get it working? As mentioned above, if someone tried re-setting the Chinese repo trip mileage wile driving the plastic gears are likely stripped. I was fortunate to have my gages rebuilt by PA Speedo. when replacement parts were still available.
3- What kind of milage are you guys getting on a 10 gallon tank? Will varie. Best to follow Roberts suggested approach above to determine your particular mileage.
4 - Is it wise to use ethanol free gas or go with an E10 Premium or mid-grade? I have always used 92 Super Unleaded without any issues in 9 yrs…. it’s nearly impossible to find ethanol free near my home.
5- The turn signal stalk has some kind of button on it the length of the stalk. What is that for? The button is likely wired to turn on/off/ flash your brights.. mine was.. You should have a small blue light above your fuel gage that can be wired to let you know your brights are on. ( sometimes it’s not wired… other times it’s wired to one of the red lights… I have seen it both ways)… also, the indicator bulb could be out. If so, you can replace with a small LED- it will make it easier to see. Cheap, brighter and will do the trick- https://www.superbrightleds.co...ight-bulbs/ba9s-ba7s. You can likely replace all gauge cluster lights with LED except your blinker lights… that one will require a resistor to blink appropriately. There may be another that requires a resistor but can’t remember off the top of my head… Happy to look this up in my upgrade files as well as send you a bulb identifier chart and additional info if needed. Best solution IMHO is to just pull the bulb to confirm what you have before ordering any LED. The guages pop out easily with a little hand pressure/push from behind the dash. On VS gauges are typically held in place only with a rubber pressure ring installed between the gauge and the fiberglass hole.
hope this is of some use, and welcome to the madness!!!
