foster461 Posted June 1, 2011 Report Share Posted June 1, 2011 My TR6 has a lot of toys, most of which are off when the ignition is off but the radio at least needs power to maintain its configuration. I'm measuring 8ma current with the ignition off. Is that what I should expect for a powered off radio or do I need to go looking for other gadgets that might be draining the battery ?

AndrewP Posted June 1, 2011 Report Share Posted June 1, 2011 8mA is next to nothing. You'd expect something to be flowing to keep the radio memory and any alarm system etc to drawn current. Last check mine was approx 150mA and thats a radio + alarm + no doubt a few dodgy earths.

The TR6 was in a trailer all winter and I didnt have time to pull the battery before it got buried in snow so the battery was pretty much fully discharged by April. I got it started with a booster and have run it for a few miles but the battery only had enough oomph to give me one shot at starting before it pooped out. A couple of days ago I left it overnight on a 2amp charger and it seems happier. I checked the current draw just to see if I had some other problem that was draining the battery but it sounds like 8ma is normal and if the battery is going flat after only a few days it is probably time to replace it.

RogerH Posted June 1, 2011 Report Share Posted June 1, 2011 Stan, Lead Acid batteries do not like being totally flat - it will kill them very quickly. NiCad's and other such things are happy in these lower nether regions and even reversed but not our old car batts. It the radio standby circuit is giving it problems in a short time then it's time for a new one. Roger Quote Link to post Share on other sites
bcthom Posted June 1, 2011 Report Share Posted June 1, 2011 I havnt measured mine, but looking at the electrical diagrams I would expect a few ma to be flowing through the alternator. May be different if you do not have a Lucas 16ACR alternator Bryan Quote Link to post Share on other sites
