Speedometer maxes out when i turn car on

Alternator pulled, any way to get the new one to fit easier?

Uhm, it should fit just as good as the old one if it's a replacement, I believe there's two alternators made but idk if they have different sized holes for attachment.

Just keep wiggling and settle with the "easier" bolt and then do the second one, make sure the idler pulley rests in that little nook or whatever iirc.

got it from a scrap yard, but it is the same bosch 120amp alternator, bolts in same spots etc. however it is a tight squeeze because i dont have the mechanical fan tool to remove it. should of got an electric fan after the transmission swap i guess. maybe i should pull of the rad hose and whatnot lol all i did was take off the idler pulley and weasled around all the other crap in the way

Got it on just have to put in freshly charged battery and fiddle with the belt until its on

ALL DONE! Start up car and battery light is still on and at 10.1 volts :s. speedometer issue is fixed? What do i do now?

Considering new alternator is in and voltage is the same with the battery being freshly charged what else could it be. As mentioned above the new alternator did stop the spedometer issue

What is the voltage while the car is running, now that the replacement alternator is in?

You said 10V was that with the engine running?

Battery connections are good and tight?

Belts routed correctly?

Is everything connected properly on the alternator?

Double check your work first.
If you had just bought a new alternator, that would be one less variable.

Yep 10.4 while running. This alternator is tested and warrantied for 60 days. Everything is tight as it should and battery cables are tight as well as the belt

Maybe connections or grounds have corrosion? What else could it be lol

Did you charge the battery yourself or get it charged somewhere?

Was the battery tested?

Auto Zone usually tests the battery for you before they charge it for free.

I just left it on the charger overnight and made sure it was fully charged before re installing it. I have yet to get the battery tested but i mean if its 10.4 while running wouldnt that be alternator related? Regardless maybe i should get battery tested?

I'm not sure, I thought about that too.

I'm wondering what it would look like on the OBC menu 9 if the battery were bad, and not able to take a charge at all.

I'm stumped as to why it's the same reading.

Check your cables, alternator/battery fuse, ground connections, positive connection by the hood area.


edit: do you have a voltmeter???

Now im at 13.4 off and 11.7 running and my speedo isnt working now it just doesnt move at all. No voltmeter

Driving 3 days now with this problem. No breakdowns, no problems at all :S wtf

Checked fuse 10,34,43 all cluster related, any others to check maybe?

as of this morning, every issue is fixed. thanks for all your help everyone

Wow...so what was the fix?

Sent from my SCH-R530M using Bimmer App

Sounds absolutely ridiculious, but the alternator must of just started to work:S the voltages are where they are supposed to be, speedo works good im happy yet baffled. Just hope it doesnt return. THANKS EVERYONE AGAIN FOR TIPS AND HELP. I did a 400+ dollar job for 80 dollars.

it was the connection gremlins!!!

glad you've got it fixed!

Awesome!

That's usually the first thing I tell my girl, when I finish a repair on the car.
