Bench testing rally gauges
I've read the IVR works by switching on and off very quickly. That's why I don't know if putting power on the IVR can be done safely or to any good effect. The cap makes sense in that it could help make the output smoother, but again others will know alot more.
Going by your photos and the shop diagram, this is what I see. If there's another way to test, I again defer to others with the knowledge and experience. I wouldn't put power through without some device to provide resistance. Is the minimum on the fuel sender zero? or something a bit above that? Hate to see a gage burned by over current.
I'm just going by how its normally hooked up.
