Tachometer Fixed with Cheap Batteries - BMW E30 DIY Project ep15
Рет қаралды 26,260
2 жыл бұрынThe 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.

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

I think you should match the voltage. An actual AA battery's voltage will be too different - should be fine if the old and new batteries have the same voltage 🤔

Yeah. I’ll validate. I just thought it was funny how they are different sizes. Thanks for making the video. Very helpful all around

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 green LEDs always light up when i turn on ignition switch. It goes off after turnign on engine. IS this also due to bad batteries?

Sorry, i haven't got a clue. Are you sure it's not just normal behavior like newer cars? Anyway a lot of the stuff I've found regarding the E30 has been on E30Zone: www.e30zone.net/e30wiki/index.php?title=Instruments#Dash_Lights www.e30zone.net/forum/search.php?keywords=Tachometer&terms=all&author&sc=1&sf=titleonly&sr=posts&sk=t&sd=d&st=0&ch=300&t=0&submit=Search

@@PorchGarage thanks. I also consult this website. But I wonder what the SI batteries are really for other than powering the tachometer. Are they also used to store service indicator lights memories?

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.

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.
