What are the advantages and disadvantages of the callee versus caller clearing the stack after a call? Here's an improved version that fixes a start-up issue and uses lead-acid battery voltages so that the dynamo's cut-out can work (simulate it here): This is set for lead-acid battery thresholds (7.2V nominal charge, 7.7 max), and adds an undervoltage lockout that forces the upper FET on and the lower one off until the voltage is high enough for the comparators to work. From what I've read, the black connection should be cut. The red one has to be connected to the positive terminal of the battery, while the black one has to be connected to the negative terminal. Low and high voltage are common terms you will hear people talking about when it comes to voltage classifications. I have a 1980 911sc and I am currently replacing the older style alternator with a new Valeo. Now that you have a system setup that outputs 0-5v, I will skip past the sampling of the voltage and move on to how to relate your measured voltage to the position of the pot. All 911s up to 1981 had external regulators and from 1982-on, the alternators had built-in ones. It only takes a minute to sign up.
