Re: 1981 380SL

Pulled speedo (Electronic no cable) because odometer stopped working..........My question, what is that capacitator looking thing that plugs into the back of it. I removed it from the rear casing and it's marked 100mA 250v.

Also, my cruise is not working. The amp and actuacter are fine, from the reading I've done here, I've tried to check for a speed sensor near the speedo, but cannot find it. Is it built into the unit? Please excuse any spelling and I hope my description is enough.

Thanks in advance!!
