Tachometer Fixed with Cheap Batteries - BMW E30 DIY Project ep15

- The tachometer on my E30 was broken, so I couldn't see what RPM my engine was running at. I fixed it by replacing the original CR14250SE lithium batteries with some much cheaper and readily available CR2 batteries (a.k.a. 1/2 AA batteries). The old batteries were welded on, but we won't need to do any welding to replace them :-)

This is my 1991 BMW E30, 318i, with M40 engine. Right hand drive, made in Malaysia. I am restoring it on my own, right here at home, in my porch, with some hand tools. The plan is to get the car to a "good working condition" so that I can use it as my main / only car.

Shopee link for the CR2 batteries I used - shope.ee/4fM9YE4TFk
Working on this on my 89 e30 cabrio. It has the motometer. When I got to this step( 7:57 ) the batteries were super corroded and they are a much much bigger size (like a aa). Should be fine, I’ll jump with wire but kinda funny. The board is also vdo even though the cluster is motometer
You the man!
Nice!
Thank you!. Just picked up am E30 and the tachometer doesn't work. I'll try this!
Hope it works for you
@@PorchGarage thank you. I'll keep you posted
Where can I buy these batteries?
Great video. Thanks!
Hi. I think they are used for some old cameras, so maybe film shops will have them - I'm not sure.
Should be easy enough to find online - look for CR2 batteries
My e30s speedometer is sometimes at zero...the sometimes reads speed inaccurately can you do one on the speedo
Perhaps you can try the suggestions on E30Zone: www.e30zone.net/forum/viewtopic.php?t=279606
hello, you did not need to remove the steering wheel? Thanks for you feedback
Did not need to remove the steering wheel 😊
@@PorchGarage thank you! 👍👍
What are the symptoms? My fuse is burning like hell, will this be a fix?
Hi. For me it was only the tachometer and speedometer which worked intermittently. I don't think the batteries would cause problems with the fuses.
Where did you get the batteries from?
Any CR2 battery will do. I bought from Shopee - shope.ee/4fM9YE4TFk
I have the early model cluster
The rpm isn’t working, so I should change the batteries?
Sorry, i have no idea. Maybe you can check on the E30Zone wiki and forum
@Elias did you find the source of the problem already?
@@mullerman1104 no I didn’t
Best option to buy a new cluster
@@EliasRizk53 Do the Interior lights work? If not it’s a fuse.
2:15 whats that exclamation point sensor for?
Hmm, I'm not sure. Maybe a check engine light? www.e30zone.net/e30wiki/index.php/Instruments#Check_Light
or maybe brake fluid level?
My original batteries are ok, 3 volts each. where is my issue?

Inicialmente reemplacé las dos baterías como se indica en el video, pero ni el tacómetro ni el indicador de consumo de combustible ni la computadora de abordo (OBC) funcionaron. Por lo anterior revisé el cableado y encontré que en el splice S319 estaban rotos 3 cables de los 7 que se encuentran en S319. Uní los 7 cables con soldadura de Estaño y en seguida todo funcionó. El splice S319 se encuentra en el cableado que está abajo de la bocina del conductor y los cables son de color rojo/verde.
I will check, thank you !!!
Need better instruction using tire scrapes to hold the batteries together.@@ludwig_der_grobe
You don’t have the bulbs in certain places because you car might not have the options
Oh, makes sense. Like ABS. Thanks!
