Do all cars have inertia switches?
All modern fuel injection cars are equipped with an inertial fuel cut off switch that shuts off the power supply for the fuel pump if the vehicle is in a collision. This prevents fuel from being pumped in case of the fuel line damage during an accident.
How do you know if an inertia switch is bad?
A bad inertia switch could be triggered by hitting a bump or tapping your foot to hard on a good song. You know where it is now so if it stalls again, reset it, drive to parts store, and replace it.
What happens if I don’t use a relay?
Another required use for relays is when you’re installing an electric cooling fan. If you wire direct, without a relay, all of the additional stress from the fan will be placed on the switch, leading again to early failure.
Is a fuse tap safe?
Are fuse taps safe to use? Higher current pulled through an existing circuit that was not designed for it can lead to problems over time with burned or scaled connectors, etc. In cases like this it would be acceptable to use a fuse or wire tap to trigger a relay which would in turn power whatever is being installed.
How does fuse tap work?
The fuse taps work by adding a new circuit to your existing fuse box. This is done by “piggy-backing” into an existing fuse slot. You simply remove the fuse from the slot you want to use, and put that fuse into the empty slot on the fuse tap. Then insert the fuse tap into the now-empty slot in the fuse box.
Can you put a fuse in backwards?
In general no. They can be put in either way. One thing to note fuses have a voltage ratings. Fuses with different voltage ratings will fit into the same holder.
Does the direction of a fuse matter?
Expert Reply: It doesn’t matter which end of the fuse holder gets used for going to the battery and which goes to the jack. Fuses don’t require current to flow through them in a certain direction so either way is fine. Always place the fuse as close to the source of power (battery, power jack, etc) as possible.
