few days ago i installed JDM speed o meter in my cuore. its RPM goes one point up and then back when right indicator is turned on. for example when engine is on, if needle is at 2, with right turn indicator on, it goes to 3 and comes back with indicator turning on and off. it has three terminals. 1- battery positive 2- ground that is shared with right turn signal. 3- rpm signal from ignition wire.
rpm works fine when hazard signal is on or door is open. this only occurs with right turn signal.
so what can be the problem. what to check?

I know this is stupid but- check if your bulbs are working properly!
My right side indicator used to work very fast when the front bulb got fused!
Good Luck!

Clearly a wiring issue, go to a good electrician he will sort it out.

Give it a separate ground.

then i tried with a 10k, 1k and 500 resistor on green wire. and with 500 ohm resistor it is working fine. i tried connecting its ground to other nearby ground but to a minor improvement. at the end main problem was increased sensitivity of meter.

Seems to be a wiring issue.

In Lahore, Faisalabad, Pindi and Sahiwal it is easily available at used parts shops. Price depends on shopkeeper 1500-2500. Ask some friend/relative to get from here The original meter is very simple. these meters with glowing needles give your car interior a modern look.
