    2010 Ford Taurus SHO - Low 5V Reference Circuit low voltage was fixed but back

    I could really use some guidance as I'm at my witts end... I have a 2010 Ford Taurus SHO with a low 5V Reference Signal (P0642). I first had this issue a couple months ago. I ruled out the three sensors on this circuit as I still had <1V with all sensors unplugged. I changed the computer but...

    Voltage tester question

    If you used a voltage tester to touch L-E does it allow the 230V to actually flow to earth or does it use a smarter means of calculating voltage without requiring a current to pass? In theory, could you damage a connected item downstream?

    Power transformer Low voltage supply

    I recently installed a 200kva, 33/0.400 KV transformer for a small commercial hostel, so after powering the transformer, we checked all the output of the 3 phase at the secondary side and it was ok but whenever a single air conditioner is powered , then the voltage becomes low. Please guide me...

    Chaining extension cords with low voltage devices

    I know there is a risk of chaining extension cords and everyone recommends against it. But I've also read all extension cords should be temporary and not used for more than 90 days - if you want something permanent you needs to install electrical receptacles (outlets). I know a lot of people use...

    Voltage on fittings in bathroom

    One of the oddest jobs I've ever had today. Called by a plumber I know who had attended after a leak through the kitchen ceiling from bathroom above - and got a shock from the bathroom tap (and his 'pen glowed on everything') Turned up to check and, sure enough, voltage of 16V AC showing on the...

    Line carrying voltage, neutral no voltage

    Hi all, I have been trying to work out why all the up stair sockets have voltage coming into the line but none of the neutrals. The ring is on a 16amp mcb. Any ideas why? Thank you in advance

    Voltage Fluctuating between 170V and 330V

    Hi, I`ve been to a site today and noticed some units I`ve got have huge voltage drops. Voltage was fluctuating between 170V and 280V and on some units, I`ve had 330V. I went to the DB board: Between live and earth some circuits were showing 217V and other one were showing 270V. Between Neutral...

    Honeywell Galaxy G2 low voltage problem

    hello all, I have a Honeywell Galaxy G2-20 burglar installed in my home (about 9 years old). Recently I got a Battery Miss fault showing on the keypad. So I replaced the battery in the main panel with a new one. It was ok for a few days, then the fault re-occured. So I checked the main...

    Multiple low voltage chargers 1 circuit

    Hi All Thanks for your help in advance. I am working on a project to wire a number of low voltage charging units on one circuit. The power will be supplied will be 20amp mains power through 2.5mm cable, each charger is 42V and I wanted to wire them about 2 foot apart. My question is how do I do...

    Grid voltage at the consumer unit of a house?

    Hello, We have installed equipment at a customer location, (or rather, an external electrical contractor installed it for us). The equipment is internet monitored by us…..and we are noticing that the Grid voltage is regularly falling to 225VAC. Our equipment disables at this low grid voltage...

    Voltage is 50, instead of 220

    There are two lights at the entrance to the kitchen. I rarely use them. Recently, I found that one light was off. After two weeks, I have finally decided to fix it. I removed the old bulb, which was labeled 220 V, 50 W. I checked the resistance and found it infinite. Burnt out, I thought. I took...

    Quick question about light switch voltage

    I have a light switch that was crackling sometimes when I would turn the light on. Swapped out the switch today, and checked the voltage on it while it was switched off. It started out at 109 volts, and slowly went down until it hit 80 volts, and stayed there. I only have one other thing on this...

    Changing IR with voltage

    On a recent EICR i have measured 0.589 MegOhms (@250 volts) on the relatively old lighting circuit (red/black PVC wiring) , i have replaced both outside lights (thinking water ingress as both were damaged). The strange part is at 1000 volts the IR changes over a few seconds to 1.6 Megohms , it...

    Voltage testing

    There has been a wide research on voltage already but my question is which multimeter can give us more accurate reading for voltage calculations, analog or an average digital multimeter like brymen or amprobe?

    Strange voltage and power factor values and installation issues

    Hi, We have installed 2 meters (each meter is a 3 phase meter) for sub-metering in a residential house (1 phase installation per apartment). One of the meters, after correcting installation, works fine now. The other one, in my opinion measures strange voltage values. We had since the begining...
