2025-09-03 New Fake Makita 9Ah Battery Ordered a new 9ah 162W/h battery off ebay and hmm it's abit smaller than my old 9ah one? either the tech's been improved & miniturised or this is a fake 9ah? :unsure: The old 9ah battery has a circuit board facing up with multiple wires monitoring...

These Denso K16TT are just regular cheap nickel coated electrodes with a thinner double-pertruding tip design (smaller area might've given a more focused spark but it wears away faster imo) My time line est it might've lasted upto 30k until that thin tip has worn down to the broad base and the...

Ah I should've checked with the nissan4u OEM charts first which shows the factory spark plugs are indeed NGK BKR4E-11 / BKR5E-11 / BKR6E-11 So Haynes says a different plug. According to cross ref, these Bosch FR7DCX are the same heat rating as a cooler BKR6E :unsure:

2025-09-02 Replace Bosch FR7 DCX Spark Plugs With the old Denso K16TT worn out, it's time to replace them. Previously I would've used the good NGK BKR5E11 but curiously according to Haynes the required plugs are Bosch FR 7 D+X with a 1.1mm gap. Hmm I dunno what the original factory plugs are...

2025-09-02 Test Headunit Max Volume vs Frequency To test how the equaliser setting & input voltage affects the max vol level just before 'clipping', I connect an oscilliscope to the output, setup the equaliser, play a sine-wave, turn up the volume until the signal begins to clip and log the max...

2025-09-01 Check Brake Wear Discs are wearing smooth & evenly All the pads wearing evenly, front inner pad has a slight lip Front brake wear is normal, the inner pads usually wearing faster than the outer Rear brake wear is also at a normal rate, inner pads wear faster than the outer

The "switched 12v feed" for the headunit, which has to run through the IGN switch & immobiliser & extra crimps, seems to get only 13.67v compared to the "constant live 12v feed" which gets the full 14.03v and the battery itself receives 14.17v :unsure: To explore if raising the "switched 12v"...

2025-08-31 Test Sony Headunit RMS Voltages Since the last time I tested the Sony headunits speaker output in June 2020, I've improved the connections & voltage supply throughout the circuit including: Nov 2022 - Replaced engine bay loom Nov 2022 - Replaced IGN loom with better crimp June...

2025-08-31 Replace Fuel Hose I was watching this video about E10 and poor quality modern cheap fuel hoses degrading/cracking, reminding me to recheck my fuel hoses 👀 The filter>rail hose and return hose (both replaced with R9 halfords hose from 2022) were fine, firm & still pliable. The oem...

Printed some blue clips the next day to contrast the red engine bay Might as well include the rainbow too lol 😅

2025-08-29 Print HT Lead Clips These HT lead supports I printed 10yrs ago are starting to warp & crack from all the heat & clamping force, & they're also a PITA to unscrew whenever I need to remove the leads & plugs :rolleyes: So a new strategy is to print more of these plastic joins &...

2025-08-29 Inspect Worn Denso K16TT Spark Plugs These Denso K16TT I fitted in 2021 are getting old now. You can see in the following pics how the sharp square tip has worn away after approx 10-20k :unsure: Here's a timelapse of the tip wearing away Time to replace them 👀

That's true 🫣 Thanks m8 (y)

2025-08-25 PWM Fan Controller Extension Wiring To make a longer & neater loom for the PWM controller, I grabbed a spare blower fan from Jack to use the extra connector terminals The newer fan on the right sits slightly further up, probably due to the rubber mount inside Same components...

I brought the cheapo small & large batteries & charger as a set on ebay yrs ago. Could it be the charger or battery controller slightly overcharging & damaging a cell over time or is it a random roll of the dice? Both batteries are also beginning to hold less total charge. Just odd how it...

With the pushrod shortened by 5mm, I bled the brakes again, started the car with wheels lifted, pump the brake pedal few times, recheck none of the wheels are binding, went for a drive and now it's working properly 👍 *Pedal has approx 20mm if initial travel before it reaches the bite point...

Managed to find an M6 screw of the correct length Pushrod sits at the right spot where the CAD model says Machined a deeper groove for an O-ring to seal onto the brake servo Filled & bled the air out of the MC like this MC & servo ready to fit While bleeding & checking brakes...

2025-08-16 Fix Citroen C3 Master Cylinder Long Travel Issue For the longest time ever since I fitted a larger Citreon C3 M/C in 2015 to match the bigger volume of the GTIR front calipers, it's always had this annoyingly long initial dead-zone in the pedal before any braking pressure is felt so...

The other day I was only briefly using this old battery grinder for just 10sec and whilst looking away finishing a task, I suddenly noticed the workshop is abit smokey only to see the lithium pack firing up! 😱 ohshtohshiiohhshyt 💩 1st time I ever had a lithium thermal runaway, I calmly picked...

2025-08-10 Convert Heater Blower Resistor Card into PWM controller Recently noticed the battery is again not fully charging up towards 12.6v cos it's only receiving upto 13.9v while the running alternator produces 14.2v 🤔 Some of the voltage drop came from the main battery 65a fuse in the...
