How does terminal 86 connect to the headlights?
Terminal 86 – Connect to the +12v power feed to the headlights (achieved by making a splice in the original loom). Also connects in parallel to terminal 30. Terminal 85 – Connect to the driver’s side door switch.
Where does the warning light go on a 12 volt car?
A warning light could easily be added in parallel to, or used instead of, the buzzer. Terminal 86 – Connect to the +12v power feed to the headlights (achieved by making a splice in the original loom). Also connects in parallel to terminal 30. Terminal 85 – Connect to the driver’s side door switch.
What are the different terminal numbers for relays?
In addition, the terminal numbering is different, using 1, 2, 3, 4 & 5 instead of 30, 85, 86, 87 & 87a. There are other relay designs that are used for some more complex applications in vehicle systems.
How many volts does a Pontiac Trans Am have?
When the key is turned to RUN, the multimeter should indicate approximately 12.6 to 13.6 volts at the positive terminal of the coil. If there is not any indication of voltage, the system likely has an open circuit between the positive side of the battery and the positive side of the coil.
Where does the power come from for a headlight relay?
The main power from the battery feeding the fuse and relays should be a nice large gauge wire as indicated. This run to the battery is typically much longer then the run from the relay to the headlights so it’s gauge must be thicker.
How big of a relay do I need for a headlight?
power and headlights they need to be much thicker. For the main feed I would try to use 10 or 12 Gauge from the battery to fuse to relays, then from each relay which should be close to the headlights nothing smaller then 14 gauge for the shortest of runs, better would be 12 gauge.
Are there any Relays under the hood of a car?
They generally are the common automotive relays that you find under your hood now. Get a relay that has more capacity then expected, some relays in the same sized packages come in various current ratings so make sure you check the specification on the part. Left Most Relay – Waterproof relay with connector.
