How does the ignition switch get power?
How does the ignition switch get power?
The Ignition Switch gets Power from Battery, which the Connection to the Battery is on the Battery side of the Starter Solenoid / Relay. The ignition switch is the master switch that provides power for the vehicle’s electrical accessories, computer, fuel and ignition systems.
How do you test a 12 volt ignition switch?
Touch the black lead on the voltmeter to the frame of the vehicle. The voltage readout on the voltmeter should read 12.6 volts. If it reads less than 12 volts, your battery is dead, and you need to replace it. Put the ignition key into the ignition switch and crank the engine.
What happens if there is no power to the ignition switch?
If fuse is good check for power being available at the ignition switch connector. If no power there, check wiring between PDC and the ignition switch-if power is up to the switch, but nothing happens with key on, no dash or warning lights, then could have a bad ignition switch. It just sounds like a maxi-fuse has blown, or a bad fusible link.
Where does the power from the ignition switch come from?
The typical arrangement is for the ignition switch power to come from the battery cable to the starter and than go to a circuit breaker on top of the engine . From there it enters the wiring harness thru a plug connection. The harness then goes to the dash area and the hot (+) wire connects to the Ignition switch.
How does the ignition switch on a boat work?
So start at one or the other and find out where you do not have power. As far as the “Other” stuff works, it is usually supplied by a separate RED power wire from the battery to the Battery switch and then to individual fuses or breakers. They may either be switched by the battery switch or by pass it depending.
Is the ignition switch on a sunesta 284 dead?
I have a 2008 Sunesta 284. When I winterized it everything was fine. When I got it out yesterday the ignition switch is dead (no power). All other systems seem fine. Radio, rocker switches, pumps, trim, all work. Nothing that runs off the ignition switch has power. I have checked all breakers and fuses.with no success. Anyone have any ideas?
How to test a no power ignition switch?
A $10 test light from an auto parts store is what you need. Hook it to the negative post on the battery and turn on the key- your small wire to the solenoid should have power- touch the tip of the test light to the terminal and it should light up.
What should the battery voltage be on an Onan generator?
A full charged 12 volt battery at rest and stabilized should read around 12.6 volts. If its too low that may be the problem…. In the event the house battery is good and full charged (assuming it feeds the genset) but still no cranking we have to look at the switch and solenoid issues.
Do you need hot wire for ignition switch?
Also, you should have one heavy gauge wire going to the ignition switch and that should be hot all the time whether the key is on or not. That wire should be fused to the battery/power bus.
