| Post subject: | alt regulator |
hey guys what is the difference betwteen a solid state and free moving or floating regulator, and when it is over charging where does it send the current, 
what are people suggesting, my alt is off a later model mini but im not sure if it has a internal regulator or if its working, i tested the altinator while the car was running and got 15volts at the alt+ terminal, will this boil the battery |

Never heard of a free moving or floating regulator on an alternator. If you are using a lucas alternator on your mini, which is the standard set up, then the charge rate should be between, 13.5 to 14.8 volts. The only way to really test it is with a good set of avr meters. The car should be run above idle, and with all loads on ie, lights, fan etc. Don't try it with a small mulit meter as it will stuff the meter and your alternator. If in doubt take it to your nearest auto electrician and ask for a charge rate check. They can do it quickly and don't usually charge for the service. |

Excess voltage is boiled off by the battery. It's a chemical process bought on by it's innability to accept any higher charge than it is built for. It will boil the charge off as hydrogen gas and also generate heat as it does so. It's not good for the car and it's not good for the battery either. |

so can i collect this hydrogen

it was giving a good 15volts at a high idle and wouldn't go anyhigher than about 15.4v so would that boil the battery, should one of these regulators that wombat makes suit |

The `regulators' Wombat makes are not for the alternator, they just reduce the 12V to 10V for the temp and fuel guages. 15.4V is too high, you need a new regulator fitted inside the alternator. |

what voltage are you getting at the battery .... that 15v at the alt could be 14.5 at the battery ??? and no you wont break your multimeter with 15v.. |
