November 7th, 2010 08:29 PM #14kung i-compute mo ang output ng terminals na nabaligtad ang pagka-series,
cancel out ang voltages, kanya = zero ang voltage na pumunta sa load.
pero ang amperahe ng kuryente between the baterya eh equal sa short circuit
ng 24 volts DC, ang taas nuon!Last edited by tip_tipid; November 7th, 2010 at 08:37 PM.

November 15th, 2010 09:56 PM #17Most electronic devices w/ transistor or IC components will be damaged by reverse voltage polarity. Unless the Electronics Engineers anticipated this accident in our car and installed protection devices. Such as fuse,diodes, ic regulator or relay to disconnect circuit from the battery.
I think the word "series" ang ginamit ng mga Pinoy Mechanic noon unang panahon. Kasi hirap sila bigkasin yun " parallel". He he he

sir, if you think that the ECM is fried... better to bring it immediately to an auto electrical shop.. rather than trying anything else... happened to me before, a friends car, japanese surplus, we mistakenly installed the battery reverse... fried everything... cost us around 15K... toyota delica i think it was.... just my 2 cents...

December 28th, 2010 04:29 PM #19almost similar thing sa akin nagkabliktad instal ng battery ng Blade trinoma staff dati...ilang fuse sira and the main one ng vios na ang tagal nila nahanp nasa battery terminal pla...
no damage to ECU and others...as in fuses lang talaga
if you're familiar with car electronic devices (I used to do electronic repairs when I was a teenager) meron reverse polarity diodes mga yan na sila sasalo ng reversal plus inductors for noise reduction lalo na sa HUs
These i saw even on the digital gauge of the vios matic...and some fried ECUs during the Ondoy aftermath

Parallel connections nga yun. I think the term "series" was from before when the car's electrical system was different, di na lang nabago and to jump-start a car, we still say "i-series", but despite of it, I'm sure the mechanic knew the correct connection which is POS to POS and NEG to NEG. Nalito lang siguro sa cables.
Happened here at the shop on a RAV 4; the moment you try to connect the last wrong clip on the terminal, mag-spark na agad yun indicating that a wrong connection has been made. Main fuse lang near the POS terminal ang pumutok.
Choice I would have made as well.:nod:
