Just curious what kind of idle power draw you would expect on a car of this era (MK1 ford KA). I was checking a potential battery issue (now resolved) and as a check for parasitic draw I measured the current with my multimeter in series across the negative terminal of the battery and...

When I say similar. I had issues with a car cold starting. No codes. Turned out there was a conflict between two temp sensors that only showed up when actually looking at the data. No engine management light came on. The coolant temp sensor was saying the car was warm, which was causing the...

Stick a basic OBD2 reader on it and check all the basic sensor readings. If you have something producing an erroneous reading it might be running in a safe mode and turning the fan on for safety, even if the engine isn't warm. Something like the coolant temp sensor perhaps. I had something...

For what it's worth, these companies are known to do this. My impression is their reps have targets or are encouraged to spot marks when the car is returned. I had a hire car while my car was in the garage. The car was delivered and I went round it like a crime scene with my DSLR to the point...

I've mused the option of just leaving it. And it would be the easier option. I was just pondering of the age of the gear oil getting on for 16+ years. Isn't it also likely that there are wear contaminates over time? (although I would expect more with high mileage vs age)

Yes, it's a manual. Yes, I think the workshop manual does say something along the lines of 2mm below the filler plug.

Not sure there is a level line. I was just going to measure what comes out and put the same amount back in. My workshop guide does not show the diagram of the drain and fill locations, so i have to work that out. And yes, I have educated myself already on the need to check the fill valve/nut...

OK....next item...thought I'd get an opinion. Car is about 16 years old now and only 40k on the clock. Gearbox seems in good condition, but I am thinking it is probably worth refreshing the gearbox oil while I am doing everything else I have read that this can end up causing issues for high...

Some pictures! First Look A clean test After a good clean Underside of cover with old gasket Engine has 40k on the clock. Car started fine, and no issues on examination on just tickover

Hopefully it starts :oops:

OK, valve cover done! Went went pretty well I think. Just slightly awkward getting it back on and wondering it is seated correctly. I'm always paranoid about knocking some connection or damaging the ignition coil which is part of the valve cover. The old gasket was not as bad as I expected...

Maybe the posts I read were mis-describing and referring to the cylinder head or something. I thought it odd, but thought I better check after the guy in that video bought new ones.

After I posted that, I looked on a few forums that these bolts could be "stretch bolts"? A once torqued you can't re-use them type. Or is this not the case or misinformation?

Just reviving this a bit. One delay after another and I never got round to doing the valve cover. So picking up where I left off here, I was reviewing that video again. I noticed that he bought brand new bolts for replacing the cover. Just wanted to check if that was a standard/recommended...

Yeh, I have learned a lot looking into all this. Been very useful, thank you to all the responders. Measuring the voltage correctly was key. Taking the measurement from the charging port was a big red herring, which initially made me think the batteries were toast. Also, understanding that the...

I looked into this a bit more. i was curious as on the website for this scooter, the company quotes up to 20mile range, but with no other information as to what D0D for the battery. So after calling their tech department, I was informed that that figure pertains to doing a near 100% DoD on the...

So I did a bit of a follow-up, and did another 6 laps 2days later (without recharging), and the results were interesting: Initial voltage after recovering for 2 days was 12.78v Lap 1: 12.54 Lap 2: 12.5 Lap 3: 12.44 Lap 4: 12. 41 Lap5: 12.36 Lap 6: 12.29 So there was a steeper drop off for the...

Ok, I did a 3 mile test. I did 6 laps on a half mile circuit and did a reading on each lap: It wasn't all on the flat, but as it was a circuit it had equal uphill and downhill. Lap 1: 12.74 Lap 2: 12.72 Lap 3: 12.69 Lap 4: 12.65 Lap 5: 12.61 Lap 6: 12.61 After all these laps I did a voltage...

After a short recovery time: New Batteries 13.11v 13.16 Old 12.96v 12.97v So both recovering, old just a bit slower than new. But, do those readings suggest both batteries are performing well for deep cycle? Or should I be using another way to assess them?

OK...the results, and they are....interesting to say the least. I took the caddy covers off and measured voltages on each battery directly with the scooter moving. I had to hold it while moving but I think I got stable enough readings. I would like some opinions on initial interpretation...
