Frax Posted March 19, 2012 Share Posted March 19, 2012 I was over to a friend house today, about 10 miles away. When I left home I found that my Defender did not start as quick as it usual does but it had been sitting for a couple of days. When I set off I noticed that my volt gauge was only reading 11.78v. When I left to come home it was back near 14v but dropped down again after about 6 miles. When I got home I put a Fluke on the battery and found it was reading 12.80v with the isolator switch turned off – turn it on and back to 11.78v. Start it up and still 11.78v. Another thing I noticed is that my stereo loses its pre-set channels. Tuned this back in and turned the ignition off – waited 5 min and turned it on again and pre-set’s were still there, however if I turn the ignition back on and turn the starter over the power goes from the stereo and pre-sets are lost. Dont know if this is just because the low start voltage drops even more to turn the starter motor !! Any thoughts welcome. Frax Quote Link to comment Share on other sites More sharing options...
western Posted March 19, 2012 Share Posted March 19, 2012 are the battery terminals tight ? Quote Link to comment Share on other sites More sharing options...
Frax Posted March 19, 2012 Author Share Posted March 19, 2012 I would say yes as they were when fitted about 2 months ago - might need to remove my seat and have a look though just to check. Quote Link to comment Share on other sites More sharing options...
simonb Posted March 19, 2012 Share Posted March 19, 2012 Anything less than 12.6V on the battery, engine off, is a duff battery. With engine on, anything less than 14v is a duff alternator. I take it with ign ON and engine off, your battery warning light is lit? Quote Link to comment Share on other sites More sharing options...
Frax Posted March 19, 2012 Author Share Posted March 19, 2012 No the warning light is unlit - with ign on and engine off. Quote Link to comment Share on other sites More sharing options...
western Posted March 19, 2012 Share Posted March 19, 2012 a good sign of your problem then, change the charge warning light bulb first. Quote Link to comment Share on other sites More sharing options...
Frax Posted March 19, 2012 Author Share Posted March 19, 2012 Would do but its an TD5 warning panel which I think is LED may need to check voltage at the back of the plug though - mind you that probably wont work - need to look into how they work, relay changes state !!!! dont know.

western Posted March 19, 2012 Share Posted March 19, 2012 Td5 warning light panel is all led, works the same as the previous bulb set up, Quote Link to comment Share on other sites More sharing options...
Frax Posted March 20, 2012 Author Share Posted March 20, 2012 Well got and fitted a new alternator today and according to my gauge I am now getting about 13v. Battery light still does not come on when I turn the ignition on so will have to have a look at that. Quote Link to comment Share on other sites More sharing options...
western Posted March 20, 2012 Share Posted March 20, 2012 possibly popped the led or it's just given up, only fix is another warning light panel. Quote Link to comment Share on other sites More sharing options...
Frax Posted March 21, 2012 Author Share Posted March 21, 2012 Will check my wiring to see if its still intact and then go from there, never a dull moment. Quote Link to comment Share on other sites More sharing options...
Frax Posted March 22, 2012 Author Share Posted March 22, 2012 Found the problem, pin had dropped out (well nearly) in the back of the warning panel plug . I remember when I did the conversion that I was determined to have good connections on all pins so I soldered every one of them, the problem I had then was the solder on some of the pins prevented them from locking into the plug.

western Posted March 23, 2012 Share Posted March 23, 2012 good to read you found the fault & even better it only cost a bit of spare time & no cash involved. Quote Link to comment Share on other sites More sharing options...
