Has anyone ever had an electrical sending unit be bad from the factory? I ordered a whole set of SW Deluxe gauges and received them last night. After 3-4 hours of wiring, I plugged everything in and started the engine. All gauges worked except the
oil pressure gauge. (I had an Auto Meter gauge previously, so I know I have
oil pressure...) The gauges are wired in series, and the
oil pressure gauge is almost first in line, so I know it's getting power...as a matter of fact I grounded the sending unit wire, and the gauge slowly went up...so I'm pretty sure the gauge is fine. Could I just have a bad sending unit? Is there anything special you have to do with a SW sending unit that you don't have to do with the others? I'm hoping there's maybe a few tricks of the trade I can try before sending this one back.
Thanks,
Brent
