Remote start using GSM relay.

0 votes
When I install a GSM relay for remote start using a mobile phone (on a yellow-black wire), it does not work correctly if I do not include a load in the circuit (a small light bulb or resistance through "+ 12v"). I've been doing this for 7 years now. What will be the reason?

The yellow/back wire on the 20 pin connector of an evoall in standalone mode does not need a load to work correctly, you can simply test this by touching the yellow/black to ground for 1 second to initiate remote starting.

I mean, it doesn't always work if we don't connect a load... Maybe a diode interferes on the GSM relay coil
