    Crazy phantom battery drain ?

    I disconnected all the unit connections and removed the wires from the radio. There was a relay that I removed together with the wiring right back to where it joined into the car loom. It's such a jumble under the dvd unit, I think the srs unit is there and it had a maze of wires. Wondering...

    Crazy phantom battery drain ?

    Hi. Had a busy afternoon. Thought I'd start disconnecting bits as you suggested. Had the satnav out and radio with display but no change. Also found a parrot Bluetooth unit have removed that and all the wiring that went to it. Don't know who put that in but wires were tucked into radio plugs...

    Crazy phantom battery drain ?

    Boy oh boy, I'm dreaming of those sort of numbers. Checked the fuses again and the only one that drops the drain right down is fuse 7 under the dash. From the list I have that supplies combination switch control, guage control, immobiliser control receiver, immoes control unit ?, navi display...

    Crazy phantom battery drain ?

    Hi. Nice day so here we go again. Took the alarm siren off and measured draw. Slightly lower at 122ma total in an hour. Amps still fluctuating 0.00 to 0.13. While it was off I took it apart - very easy, two screws. Battery pack is 6 button cells soldered together, connected to pcb with computer...

    Crazy phantom battery drain ?

    I guess it's because it's connected to the car battery virtually all the time. No idea how it's supposed to charge but there must be a voltage dropper/ regulator built in. Really hope it's this trying to charge and wobbling the current drain. It's got to be first on the list.

    Crazy phantom battery drain ?

    Point taken. I hope it will be ok to disconnect without the alarm set then check to see if the current fluctuation goes away. That's why I tried earlier to see if it was still there with the car unlocked.

    Crazy phantom battery drain ?

    Just checked the alarm again. Hand I through window alarm set off loud. Remember alarm went off last week when disconnecting battery. ( must have locked up before doing that ) and it was very quiet. Sounds like the battery in the siren is giving up ghost. We shall see.

    Thanks. The guy who fitted the reverse sensors took 5 minutes to get the trim off. So it can't be that difficult. Lol. Yes typo error. Resistor. Sorry, heads going now. Need to calm down and think logically.

    Crazy phantom battery drain ?

    Hi, yes a manual would be useful. I'll have a look later. I have established the siren is on the drivers side of the boot. Had a quick look and theres a load of poppers and rubber trim to move to get at it. Have to go out later so no time now. Just as a matter of interest regarding the...

    Crazy phantom battery drain ?

    Hi. Yes I know dmm is digital but my dmm keeps blowing the 200ma fuse. Have to set it on 20a but then when the cable is moved to the ma socket the surge blows the fuse so I use a old ****ogue avo that only uses one socket for all the scales. Hence the quivering needle. I wondered if a higher...

    Crazy phantom battery drain ?

    Hi there, no everything has always worked. Must have blown a couple of fuses messing about. Still monitoring, though it looks like a constant drain - the hourly differences are all pretty much the same since 8.30 this morning. Strange how the Amp and Watt displays are jumping around. I guess my...

    Crazy phantom battery drain ?

    Hi there. I know about the bonnet lock trick. Need a strong screwdriver to lever it over. Think I'll put the meter on it for the day tomorrow but if there's no luck will have a chat with honda on Tuesday. I came across a honda instruction sheet for using hds to query micu and there are so many...
