brassbones Posted October 19, 2017 Share Posted October 19, 2017 Just tried jump starting my supra with the jump pack and I think I put the crocs on the wrong terminals!!! Yeah, I know, it was dark and I'm a dick. Now the lamps are working but not a squeek out of the ignition. Have I blown a fuse and if so which one?

jagman Posted October 19, 2017 Share Posted October 19, 2017 The ignition module instantly is destroyed and is now scrap Quote Link to comment Share on other sites More sharing options...
brassbones Posted October 19, 2017 Author Share Posted October 19, 2017 Expensive fix? Quote Link to comment Share on other sites More sharing options...
jagman Posted October 19, 2017 Share Posted October 19, 2017 Around 100 quid new , soarer aristo use the same module and plenty of used ones around as they never fail unless cross connected -used ,I guess 10 quid to 80 quid depending on the sellers greed ability , ive probably got 2 or 3 in my shed and they will never be used as they never go wrong - vvti modules are different and they also never go wrong unless x connected !!!

jagman Posted October 19, 2017 Share Posted October 19, 2017 I guess keron would have about 432 of them and only ever sells them to the "JUMP STARTERS"- welcome to the jump starters club -lol Quote Link to comment Share on other sites More sharing options...
mattdavies Posted October 20, 2017 Share Posted October 20, 2017 You may of just blown the big 120amp fuse, it is on the far left as you look at the fuse box in the engine bay Quote Link to comment Share on other sites More sharing options...
Al Massey Posted October 20, 2017 Share Posted October 20, 2017 You may of just blown the big 120amp fuse, it is on the far left as you look at the fuse box in the engine bay Possibly this, I have never blown the ignition module when trying to jump start and have the polarity the wrong way :/ Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted October 22, 2017 Share Posted October 22, 2017 No that's a relay. In the engine bay fusebox you will find the 120amp fuse circled in red below Check the metal fuse hasn't burned / split in two pieces Quote Link to comment Share on other sites More sharing options...

jagman Posted October 23, 2017 Share Posted October 23, 2017 the 120 amp fuse feeds another 50 amp fuse this feeds some circuits off the ignition sw, some of the ignition sw circuits are directly fed bypassing the 120 a fuse- the starter circuit is fed from either or ign 1 or ign 2 -if the 120a has blown then the 50a would probably blow too IF the ignition switch was turned There are a few IFs , that can have an effect , was your foot on the brake pedal and so on - these make circuits and allow the reverse polarity to cause problems ,regardless of these the ignition module frying is the most common effect . To diagnose any electrical problem you need all the symptoms ,you seldom, if ever get this - lamps are working ,which lamps , not a squeek out of ignition - nothing at all ? there are 2 ignition circuits , did you try and crank the engine ? Maybe you burned the ignition switch contacts , maybe a few fuses gone or wire burned . you need to test with a meter in a logical sequence Quote Link to comment Share on other sites More sharing options...
brassbones Posted October 24, 2017 Author Share Posted October 24, 2017 Cheers jagman. I've got a new 120A fuse and have the indy coming out next monday. I'm hoping its just that, if not Keron does the ig pack for £45. Just hoping it's not a clusterf*ck Quote Link to comment Share on other sites More sharing options...
