Ok guys, today we are going to continue sharing good info, on how to DIY the Installation of Ammeter and Voltmeter performance gauge in a car. For those who need to monitor your car battery / DC power constantly for ICE etc, please take note to do it yourself. Basically, you can buy the volt and ampere gauge or meter at around RM40-100 and install it your self. It is quite a fun thing to do on your car.
HOW TO INSTALL PERFORMANCE GAUGE – AMMETER & VOLT METER INSTALLATION
You need to buy the volt or ampere meter, with the meter holder with stand (like above) or without stand, 3 meters wires and an electrical tape. You can buy any design or type of meter or gauge that you like. The installation circuit is the same for all. Some famous brand are Autogauge, Type R and Jasma meters.
Above picture is voltmeter and the back of it is the ammeter. Some meter is provided with the black cap like the one shows above which has been fitted on the meter.
You can see a rubber band like “o” ring seal fitted on the gauge’s body for fitment of the meter in the meter holder. If there is no rubber band, you can use double sided tape.
There are 4 point which you need to connect with battery source. The two wires on top of the picture which usually ready made on the meter is for meter lighting power source. While other two is for volt/ ampere reading.
You need to connect another 2 wire at the bottom of the meter like above which written there “+” and “-“. The +ve wire in red is connected to +ve red wire and -ve to -ve black wire.
Then you can put the meter into the meter holder. Picture above shows boost meter with long tube. Ignore the tube / host because voltmeter and ammeter do not have the hose actually. That is for boost meter and vacuum meter only. I just forgot to take picture with volmeter =p
Connect the two wires to the power source (battery or other source) that you want to use as lighting for the meter and other two red and black wire to your battery for batter volt or ampere reading. use the diagram above as a guide for ammeter and voltmeter circuit installation. Put red wire on +ve red battery terminal and black wire to -ve battery terminal and bring the wires into the car cabin via a hole between the engine bay and dashboard.
After all wire connection done, secure it with electrical tape properly and you can test the meter. Remember to put 10/15/20 ampere fuse between the wiring diagram just before red +ve terminal of car battery. Don’t worry of anything because if any wrong connection, only the fuse that will be burned. All car electric device are totally safe. Just replace the fuse, do the right connection according to diagram and test it again.
Good luck! =)
