alternator

Post by elfin girl on Mon Dec 29, 2014 4:14 pm

im after a working alternator for a 99 1.3 hijet. or if anybody knows any companys selling links would be great

sick to death of my battery dying every winter, every mechanic says the alternator is fine (not one has checked it!) but im pretty damn sure its not puting out enough to charge the battery.. through the summer the battery has just enough power in the mornings to start it. come winter when i need the lights, blower ect it eventualy gives up due to lack of power... now in my eyes if the lights dim as i switch on more electrical stuff there is something up with the alternator. if anybody else thinks it may be somethong else feel free to offer your theories !

Check the voltage at the battery when running.

Should get 13.8 or more if the alternator is good.

I would be suspicious of the battery. How old is it and how is it rated (Ah, amps and test standard SAE, EN, DIN)?.

battery bought last winter, to replace the one i bought the winter before... cant remember the ratings but same as the one that was in van when i got it that lasted four/five years after i got it.
till i started noticing loss of power when more electrics used.
im just having a look at the booster battery things as was considering getting one anyway. for a bit of extra power when camping.

essentially even when the van starts there is not enough power being generated to run the lights and the blower (lights dim more with each electrical instrument switched on) so yes the battery is most likely shagged... the most likely cause being that it never gets properly charged while in the van. in summer i just about get away with it but come winter i cant drive short distances or in the dark or cold because otherwise the battery doesnt get enough charge to start it up the next time!

three days a week i do two to four 5 min drives to work, dog walks, not enough to recharge, the other four days either two 20 min drives or none at all then the occasional 30-60 min drive at weekends. then the odd several hours of driving.
the week before it died i had been doing a fair bit more driving about, 45 min journeys but mostly needing lights and blower going

so battery booster is on charge. hopefully this will keep the van battery going for longer. a much cheeper option than buying an alternator and finding battery still wears out. and the booster is multi function, has a pump, light and cigarette lighter socket so should come in handy when camping

oh.. and i found my multi meter so at leats now i can check the volts and see whats going on when the van is running

If you can lift the caps on the battery, get someone to hold the key in the crank position(even though it's not turning over) and look in the cells, if any are bubbling yer battery's goosed.
