 +====== Alternator Diodes ======
 +LR put a diode in the alternator warning light feed to prevent back-feeding which can lead to the vehicle "​running on" when there'​s not enough load on the ignition side circuit to pull the wire down to 0v when you turn the key off.
 +However, if one or more of the diodes in your alternator fails, normally it would light the light when you turn the ignition off - but with a diode in-line this wouldn'​t happen and you'd only notice once all the diodes failed and your car caught fire.
