A relay board is an electronic circuit board that contains multiple relays, which are electrically operated switches. It allows a low-power signal to control larger loads, such as motors or lights, by isolating the control circuit from the load circuit. Relay boards are commonly used in automation, robotics, and home automation systems to enable remote control of devices. They can interface with microcontrollers or computers for programmable control.

Were is a dme relay located on a 1985 Porsche 944?
1985 was a changeover year for the 944. Early cars (sometimes refered to as 1985.1, with three separate round guage pods in the dash) have the DME relay located on the relay board in the driver's footwell, under the dashboard. The DME relay is in position 2 of the relay board, second one from the left. Later series cars (1985.5) have the fuse and relay board under the hood, on the left hand side, just in front of the windshield. Open the box up and there should be a diagram on the inside of the lid.

How do you tell if your 1998 Audi A4's switch is bad or if it is just a relay?
best way to test a relay is remove it from board, get a 9v square battery and touch the switching terminals on the relay, the relay should click if its working. You can then test resistance through the relay. You can also check the feed to the relay, if theres pwer to the switching terminals on the relay, chances are the switch it ok. If no voltage, switch or wiring.
