there should be a diagram on the side of the relay with the pin numbers and some symbols. the pins that are on the coil or control side can be wired power and ground. this generally goes through a switch. the load side has a small gate looking symbol these can be wired power and ground either way and this is the side that you connect to whatever you are powering on. make sure to use a fuse on this circuit on the power lead.

Follow the schematic of the relay.

A relay is simply an electrical switch that is operated by an electric current.

When current is present at the relay coil, the relay toggles the switch.

If you do not know how to read the schematic of a relay, you probably shouldn't be messing with it.

Can a 12 volt battery safely run a 9 volt motor?

Running a 9 volt Motor on a 12 volt BatteryUsually, I have gotten away with this, BUT... depending on the quality of the windings in the motor, it could burn through the tiny wire in the motor winding. I have done this many times with no problem, but have also burned out a few motors.One good example is that I have several [from the "early" days] cordless drills. The early ones used anywhere from 6 to 9 volt battery packs.I then bought a 12 volt drill at Harbor Freight and Tools, and when I got it home and examined it I realized that the 12 volt battery pack was IDENTICAL in size to the older 6 and 9 volt packs.So, after charging the new 12 volt pack, I tried it in the older 6 and 9 volt drills. Lo and behold, it worked fine, with just a little more RPM and drilling power.I then called my Electrical Engineer brother and asked him about it and he said that those small drill motors are not that sensitive to even a doubling of voltage and perform OK with 12 volts on 6 and 9 volt units.That was about 4 or 5 years ago, and for some time, I've been using 12 volt battery packs for all three units [6, 9, and 12 volts]. When time came to replace failed 6 and 9 volt units, I switched to 12 volt packs for all 3 drills.Again, I think 12 volts will be safe for your 9 volt motor, but it depends on the motor.


How do you check for amperage draw in a 12 volt car electrical system?

Place a current meter (rated for several hundred amps) in series with the battery. Or Place a large gauge wire of known resistance in series with your battery, use a high precision volt meter to measure the voltage drop across this piece of wire, then divide the measured voltage drop by the resistance of the wire. This will give you the current traveling through it.

How do you wire a relay for aux lights on a truck?

This would be a standard procedure for any 12 volt negative ground vehicle. Using a typical generic automotive 12 volt relay, notice that the connections on the relay are numbered 30, 85, 86 and 87. Each connection has a generic function. You would wire a relay for aux lighting as follows, Number 30 would be connected to a 12 volt fused power source from the battery. Number 87 would be connected to the positive lead for the aux light(s) not to exceed 300 watts per relay. Number 85 would be connected to chassis ground. Number 86 would be connected to the 12 volt lead from the manual control aux switch.
