Hi would heated grips added to a honda transalp 600 cause the batterie to boil.thanks
No--but.... Heated grips will only put an added load on a battery, and that won't cause boiling of a battery. What WILL cause a battery to boil is overcharging or charging at too fast a rate. Now, then--when you add heated grips to the bike and you make a mistake somewhere in the wiring, you can affect the charging rate, and it's possible that a voltage regulator/charging system sees more current being drawn than it's used to and it's trying to replace that current as well as charge the battery, and it's feeding a higher voltage/current to the battery than was intended by the designers. You can check this out--put a voltmeter on the battery terminals, run the engine, and turn on your heated grips. A normal charging voltage for a vented lead acid battery should be about 13.8 to 14.4 volts; yours may go a little higher. If you're seeing a lot higher than 14.4 volts, you either have a defective voltage regulator or perhaps such a bad battery that it's screwing up your charging circuit.
