Oxford heated gloves problem

Someone's given me a NOS pair of Oxford heated gloves as a thank you and they have an odd problem.

Connected direct to the battery they work perfectly right up until the point you start the engine and they switch off.
Seems there is a voltage regulation problem with them, anyone run into this before and got a cure?

Can you switch them on again, or are they dead once the engine is running?

If it is the high voltage you could use a 12v to 12v stabiliser. Trouble there is what amperage do the the gloves use, anything over 3 amps is getting intp the probably not worthwhile range.

Just in case you've got them set up with shorter wires for testing, make sure you have them set up as if you're going to use them, with all the long extension wires to route up your jacket, down your sleeves etc. They may get a bit less sensitive with a full length of wire, a bit like heated grip instructions tell you not to shorten the wire too much.

Are these intended for bike connection? Some gloves are 7v battery only, and may have over voltage protection. What model number on the gloves?

I assume by "works", it has an led on the controller, which goes off, along with the heat, when engine is on. First Id check wires for dodgy connection.

Connect it up to variable voltage supply. Try 5-15v and report back if it has the same issue and at what voltages.

Keis gloves have the same problem and still supply the inline resistors for £5 so ordered a set but unfortunately they use a different connector so also ordered a Y cable and will get the soldering iron out make up a modified cable and see if it works.

Cables are all made up with the Keis inline resistors on each side and the gloves work fine now.

it seems there is some kind of regulation concerning heated clothing specifically heated gloves that they can only achieve a certain temperature which I suppose makes sense, no one wants burnt hands.

As the temperature settings are achieved by using a pulse width module they aren't really temperature settings as such more power settings in that the PWM switches on for a percentage of the time. Full power its always on, half power its on for half the time but it switches at a fast rate, probably about 50 or 100 times a second or something like that. the more it is off the lower the perceived power.

Anyway they are all sorted and work well, just tested them on a quick 10 minute ride and they warm up quickly giving a good spread of heat across your hands. The are very bulky compared to the summer gloves I normally wear year round, bit of a bother to get under the cuffs on my jacket but still just about fit inside my Tucano muffs so they are usable I just wouldn't want to be taking them on or off too much.
