felixx Posted May 23, 2015 Share Posted May 23, 2015 So a couple of weeks ago alternator light would flicker at idle in Anglia (above 1500rpm all good, a steady 13V or so) Today, Anglia had a flat battery (after sitting for 2 weeks) I jumped her and voltmeter in car said 12V (I thought - All good, it will be low as battery was flat) Took her for a hoon up the road and back, voltage less than 10v (No alternator light when the engine is running) Is it my Alternator or battery?(Or Both) Quote Link to comment Share on other sites More sharing options...
Hemi Posted May 23, 2015 Share Posted May 23, 2015 Weird the light isnt coming on , check voltage @ battery with engine off , then with engine running at high idle (1000 rpm) should be around 14 volts . if its less then 14 but mroe then original battery voltage then its charging but maybe some of the diodes are knackered. a sparky should be able to chime in here.

flyingbrick Posted May 23, 2015 Share Posted May 23, 2015 Could just be a bad alternator warning lamp 1 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 23, 2015 Share Posted May 23, 2015 try battery from daily? Quote Link to comment Share on other sites More sharing options...
Bling Posted May 23, 2015 Share Posted May 23, 2015 I have a good charger I can chuck battery on to rule that out if you don't have one. Quote Link to comment Share on other sites More sharing options...
Frosty Posted May 24, 2015 Share Posted May 24, 2015 Are you sure it even has an alternator? The Angia has a Generator with a seperate Regulator unless it's been converted. 13 - 14.5v is normal charging rate. Light flicker at idle is normal, the more revs the more amps so the light goes out. No light at all means on amps at all. First check is easy, just wind up the idle to 2000rpm and check voltage at the battery, it should be more than 13v, if it is then it's just the bulb. If not then. Worn out brushes or a dirty commutator in the generator. Regulator can also be out of adjustment. Bearing wear can also cause problems. Workshop manual will tell / show how to fix / adjust both. Or drop me a PM and I can copy from my manual. Quote Link to comment Share on other sites More sharing options...
felixx Posted May 24, 2015 Author Share Posted May 24, 2015 It has an alternator, I jammed one in in 1992 when I got it. (Stereo was installed same day) It is odd the warning light does not come on. I have another battery. I will jam it in wed as I spent all day getting subaru up to wof spec before selling it Regards Glenn Quote Link to comment Share on other sites More sharing options...
Frosty Posted May 25, 2015 Share Posted May 25, 2015 No light at all with an alternator is brushes or a bad connection, almost always but discharging the battery in two weeks would indercate the diode pack needs help or you left something on, ether way you won't know for sure untill you get a charged battary back in and check the voltage when the engine is running. Before you get deep into the $ pit check the connections, the bullet ones found everywhere in an Anglia but in this case the ones in the engine bay, they often rust inside and because they are hidden by a black plastic cover you never think they are the issue. Untill they are and you spend two days trying to get a park light going. The Ford alternators from the kent cross flow engines always gave problems even when new. If I was in your place I would put a late model japa one in and be done with all that english quality electrics stuff. This is coming from someone who has loved, owned, driven and fixed Classic English cars for the last 35 years. Quote Link to comment Share on other sites More sharing options...
felixx Posted June 7, 2015 Author Share Posted June 7, 2015 Hi team.. Well I finally got around to charging my battery.. Had to buy a new charger as I lent mine to someone but cannot remember who Battery was happy, car started nice and mantained about 14v while running I think that she had been sitting too long and maybe the battery just needed some love Will try a cruise later in the week, round and round the block with the lights on and see what happens. If it drops.. I will get the diodes checked Thanks for all the good advice Quote Link to comment Share on other sites More sharing options...
ajg193 Posted June 7, 2015 Share Posted June 7, 2015 Just keep it above idle speed, battery will go flat if it is idling with lights on. Should make a mini oldschool cruise of following felixx around. 1 Quote Link to comment Share on other sites More sharing options...
felixx Posted June 8, 2015 Author Share Posted June 8, 2015 Well I did 20 min of hooning with radio cranking and headlights on and heater fan running She stayed at 13V with all this going (this is everything I could turn on, on) when they were turned off she went back to 13.9V I will tentatively call this fixed ? 1 Quote Link to comment Share on other sites More sharing options...
