| Apr 1, 2019 at 13:57 | comment | added | Johannes | If there is enough leakage to GND to enegize the relay. Wouldn't it be the same leakage with fig 3. Ford Ranger EV is electric pickup. And the 12V battery is drained because of electronics with power all time. | |
| Apr 1, 2019 at 9:26 | comment | added | Transistor | So where is the leakage with Figure 3? What is a Ranger EV and why is that relevant? | |
| Apr 1, 2019 at 8:33 | comment | added | Johannes | Just want to have as low idle drain from the 12 battery as possible. The Ranger EV in original state is a terrible battery drainer. 14 days idle and it won't start. So I'm trying to lower this for every modification. Maybe some extra diodes would help? | |
| Apr 1, 2019 at 7:49 | comment | added | Transistor | Figure 3 solves the problem with minimal change to your layout. Why do think you should replace the ULN2003? | |
| Apr 1, 2019 at 7:02 | comment | added | Johannes | Thanks, very clarifying. Will try this asap. Do you have any suggestions to replacement of the ULN. Maybe a SSR? Would that solve the problem. | |
