Checking for a Good Ground
After installing the ground kits, use a multimeter to confirm that the seat and printer are both grounded properly.
To check for a good ground connection:
1. Turn OFF all accessories, including the dome light, to prevent other currents from distorting the reading.
2. Take a multimeter and measure the resistance between the brackets the two ground strap bolts are fastened to. Find a clean
spot on the brackets without paint to use as contact points. Other bolts on the brackets are often suitable.
2a. If the resistance is less than 3Ω, the system is grounded adequately.
2b. If the resistance is still greater than 3Ω, check for proper metal to metal
contact on both ends of the ground strap. Clean any paint, dirt, or oxidation
that may block the grounding point. If the resistance remains above 3Ω,
attach the ground strap to a different ground point. Repeat the process until
the ground resistance is below 3Ω.
If the multimeter reads “MΩ” or “KΩ”, typically,
one of the accessories is still on.
