Roman 14,662 Posted March 15, 2019 Report Share Posted March 15, 2019 You need to run the voltage sense wire all the way on its own to the battery. Or otherwise diagnose it further. Buying a new battery isnt the fix here. 2 1 Quote Link to post Share on other sites
flyingbrick 9,433 Posted March 16, 2019 Report Share Posted March 16, 2019 David is right as usual. Run a nice new sense wire over to the battery positive and check volts again. Quote Link to post Share on other sites
bonkas 209 Posted March 17, 2019 Author Report Share Posted March 17, 2019 My issue is I am retrofitting a newer 90s alternator and only using the sense and bulb wires, auto electrician said voltage would be high as it is not computer controlled. Not sure there is any way around this without putting old anemic one back in... When I tested the sense wire it had exact same voltage as at battery, will need to check again.

Auto electrician is not making sense. Computer controlled alternator my ass. How exactly is it wired? Quote Link to post Share on other sites
bigfoot 1,360 Posted March 17, 2019 Report Share Posted March 17, 2019 I have an RVR alternator on my LB. Used the 2 wires that went from the alternator to the loom(instead of the external reg) Works well so far, pumps out 14.7v to battery in boot Quote Link to post Share on other sites

The alternator was tested and put out ~14.5v which I was happy with but 15 just seems too high. I have had to charge this battery a few times, maybe this is the issue... Maybe if I give it time the voltage will drop as battery charges.. The battery was only at around 12.2 resting voltage when the car was started. Quote Link to post Share on other sites
bigfoot 1,360 Posted March 17, 2019 Report Share Posted March 17, 2019 What was your alternator from? As far as I remember, it was only the really late alternators (evo 8 on) that were ecu controlled. Mine was from a n23 rvr, plenty available and bolt straight on. Also keeps it simple Quote Link to post Share on other sites
bonkas 209 Posted March 17, 2019 Author Report Share Posted March 17, 2019 Was from a 96 Lancer Quote Link to post Share on other sites
bonkas 209 Posted March 22, 2019 Author Report Share Posted March 22, 2019 Hmm there is voltage on the wire to the sense pin... maybe it's a dodgy connection in the plug/alternator.. would this be a fault of no voltage on the sense pin? Quote Link to post Share on other sites
cletus 40,955 Posted April 5, 2019 Report Share Posted April 5, 2019 Carbs sound cool @1.54 in your video sounds like it is pinging though, might be too much timing? Quote Link to post Share on other sites

Haha, yeah! The noise went away when we took out the loose catch can we realised was left rattling around in the engine bay Quote Link to post Share on other sites
Roman 14,662 Posted October 3, 2019 Report Share Posted October 3, 2019 Awesome result! That's some great power, especially since at a fairly low rpm Look forward to seeing how it goes when it's running a little richer. Bring to drag day plz! Quote Link to post Share on other sites
bonkas 209 Posted October 4, 2019 Author Report Share Posted October 4, 2019 Dunno 'bout drag day @Roman but will definitely be at 2020 nats! The bucking misfiring feeling when cruising has put me off driving it too far. This was not an issue before they dicked with my distributor so I suspect it's timing related. It does seem quick but the slow gearbox and my slow brain make for some very slow gear changes and the gears run out fast haha. Also @Roman the voltage seems to have settled down to about 13.9-14.4v now, not sure what was going on, flat battery doing wierd stuff? 1 Quote Link to post Share on other sites
Roman 14,662 Posted October 22, 2019 Report Share Posted October 22, 2019 Post fuel economy dataz when you return plz So far a lot more impressed with this setup than I would have imagined. Suits the car so well too. This whole thing is just great. I'm sure you'll have worked out all of the niggles soon enough. Quote Link to post Share on other sites
