slow starter when warm

[feyaz]

hi, my starter on my 3.9 1989 rangie turn over very slowly when warm/hot, sometimes turning over so slowly and jerky I can count revolutions.

is it a common problem, possibly a new starter, or just loose connections? if loose connections then am I looking anywhere but the obvious?

thanks in advance!

mind did that when the timing was a bit out, felt like it had a flat battery.

timing? ignition timing?

might be stupid question, but I've just got this range after having a pretty maintance free cavalier v6.

yeah thats it has to be set with a timing gun, mine was a bit out after removing then replacing the distributer the car would turn over very slowly like the battery was flat, re-set the timing and problem instantly solved might be worth a go.

may just be a case of the starter being a bit sticky, may need to remove it and give it a grease up and check any connections you can see, are you sure the battery is fully charging? make sure the alternator connection is ok otherwise the battery will slowly drain.

if your new to land Rovers get used to things like this happening :lol: its part of there charm..they can be a love hate relationship

hi, I will check the timing, but I was a bit confused by the timing issue since it only really struggle to start when hot. by stuggle to start I mean turning over very slow.

I have tried the jump leads to the starter, also jump starting with my other car and charging battery. no change

I believe it could be the starter itself, so will remove and clean up, otherwise I'll get another one. I have been search for new one on the net they show "geared" starters to make it turn over faster, and what I believe are standard, if I  do need a new starter which one do I go for considering the quicker starter is 3-4 time the price.

thanks

to be honest im no expert on all the different starters, but theres defo atleast two types the early version which is a bigger unit and a smaller later version, i have the smaller version i think its more powerfull too, as you have a 3.9 then you probley already have this one, maybe worth poping into a local specialist garage and let them have a look before you start spending money on a new item, if you ask on here someone may have a good used one that they will sell to you. i think i would try using a voltage tester to see if full power is getting to the starter, try it form cold and then from hot and see if theres a difference, could be a dodgy earth somewere, normly if i get silly problems like this and i can get it started i run it to my local landy specialst saves a lot of messing about, more oftern than not they suss it out in a few minuits and dont even charge me, its worth building up a good relasionship with them, i have over several years and several grand lol..
you could also try asking on www.lro.com you may get some other ideas there..

but from what you have said it sounds like the stater its self, cant explain why it works fine when cold though..

i use a great garage nr Romford if thats not to far for you

a geared starter has cogs in it to reduce the speed of the output gear thus making the starter draw less current/give higher torque. but no matter which starter you buy, it should turn your engine over reasonbly quick so it starts.
your problem could be that your alternator is not charging your battery quick enough (alternator knacked) thus after your engine has been started and the power has been drained from the battery, when you switch your engine off there isnt enough power to start it again.

or could be a faulty starter.

this is assuming youve checked the earths and the thick positive cable to the starter. remember when checking these bigger cables, to acually remove them and clean them with an emery cloth, as it could have a bad connection even though the studs are tight.


a few checks you can do.
measure the battery voltage when the car is cold and then when the car is warm (both with engine off) the voltage should be over 12volts DC in both cases. (i would expect the voltage to be higher when the car is warm)

check the charge voltage of the alternator, with the engine running after about 5 mins, check the battery voltage, (with engine running) and it should be over 13volts (i would expect 13.5 upto 14.5).

let me know what you find.
