fmlycar Posted November 12, 2015 Share Posted November 12, 2015 I recently installed a wideband in my s1 c34 stagea. I cut the power and earth from the clock and used those. Now my problem is, now my dash doesn't store the trip a and trip b kms traveled, it just wipes it every time I turn the car off. Is the memory for that run through the clock loom somehow?

fmlycar Posted November 12, 2015 Author Share Posted November 12, 2015 Problem solved. Clock fuse was blown Link to comment https://www.sau.com.au/forums/topic/460990-trip-meter-memory/#findComment-7637396 Share on other sites More sharing options...
Trex Posted November 12, 2015 Share Posted November 12, 2015 I would be worried about why it blew. Why did you use the clock power? Afr gauges should be run through a relay from battery power.

Hadouken Posted November 12, 2015 Share Posted November 12, 2015 they don't have to be run through a relay. It is just like wiring any other gauge or head unit. a afr gauge is not going to draw that much current to warrant a brand new power run from the battery. using the clock is a interesting one for a power source. the fuse probably blew while he was tampering with the wires.

Hadouken Posted November 12, 2015 Share Posted November 12, 2015 I am only speaking from a electronic point of view, why bother running all that wire which is not needed. I know id rather keep the cabling as short as possible. Link to comment https://www.sau.com.au/forums/topic/460990-trip-meter-memory/#findComment-7637462 Share on other sites More sharing options...
Duncan Posted November 12, 2015 Share Posted November 12, 2015 wideband controller will draw up to 5A because of the 02 sensor heater. I would be careful about what I tap it into, but agree a relay seems like overkill Link to comment https://www.sau.com.au/forums/topic/460990-trip-meter-memory/#findComment-7637464 Share on other sites More sharing options...
Hadouken Posted November 12, 2015 Share Posted November 12, 2015 here is the install from the manual. If you read carefully it does not say you "must" use a relay. Says if in doubt. And draws 3 amp, your cigarette lighter draws more lol Connect the RED wire to an isolated switched 12V source in your vehicle. A switched 12V source goes ON as soon as “key on” power is active. The circuit to which you will pull power from should be able to support a 3 amp draw. Make sure this connection is protected with a 5A fuse. Circuits that share power with the vehicle’s stereo, ignition system, ECU, lighting, or fuel pump should not be used. When in doubt, create an additional circuit using an automotive relay available at any automotive parts supplier. See the next section for a relay installation diagram. The BLACK wire should be grounded to a solid ground source. The best possible ground source would be the battery ground (-) post. 1 Link to comment https://www.sau.com.au/forums/topic/460990-trip-meter-memory/#findComment-7637466 Share on other sites More sharing options...

fmlycar Posted November 12, 2015 Author Share Posted November 12, 2015 (edited) Yeah hadouken I must have done it when I was moving wires about when I was in there with the test light. That circuit has a 10A fuse, and given the wiring was already there and that's where I wanted to mount my afr display anyway, it made sense to tap into it. And as I've already found out, if it does trip the fuse, only the trip reading and clock are affected so I can still drive the car.

Hadouken Posted November 12, 2015 Share Posted November 12, 2015 Oh right. That's actually quite neat Link to comment https://www.sau.com.au/forums/topic/460990-trip-meter-memory/#findComment-7637557 Share on other sites More sharing options...
