H\u00e4r kommer en lite uppf\u00f6ljning p\u00e5 mitt senaste blogginl\u00e4gg om Ad-bluestrulet. Det var d\u00e5 en magnetventil p\u00e5 g\u00e5ng med f\u00f6rhoppningar om att det var det som var felet, s\u00e5 var det inte…<\/strong><\/p>\n

Fel fel…<\/h3>\n

Att hitta r\u00e4tt fel \u00e4r ibland en av de stora utmaningarna n\u00e4r man skruvar.<\/strong> Det \u00e4r inte alltid s\u00e5 l\u00e4tt som n\u00e4r en bakaxel g\u00e5r av att hitta vad som \u00e4r trasigt.. Det finns massa fina felkoder att f\u00e5 i en traktor, men de \u00e4r inte alltid de pekar tydligt p\u00e5 vad som \u00e4r fel. Stoppar n\u00e5gon med beh\u00f6righet in en dator kommer finns st\u00f6rre chans att man hittar r\u00e4tt fel, men det st\u00e4mmer inte alltid. Uteslutningsmetoden fungerar ocks\u00e5 bra i m\u00e5nga fall. I det h\u00e4r fallet fungerade felmeddelandena sis\u00e5d\u00e4r bra, men gav indikation p\u00e5 vad som var fel och det utgick vi ifr\u00e5n. Det ledde oss i arbetet n\u00e4r uteslutningsmetoden p\u00e5b\u00f6rjades och begr\u00e4nsade tyv\u00e4rr fels\u00f6kningen till endast uppv\u00e4rmningen av Ad-blue systemet. Det slutade med att vi sp\u00e5rade felet till en magnetventil, som dessutom enligt uppgift visade fel Ohm vid m\u00e4tning. Ny ventil best\u00e4lldes och d\u00f6k upp. Tyv\u00e4rr s\u00e5 hj\u00e4lpte det inte alls, det var dessutom samma Ohm p\u00e5 den n\u00e4r jag m\u00e4tte s\u00e5 detta var ett snesp\u00e5r som tyv\u00e4rr kostade lite mycket tid…. Det var fel fel helt enkelt…<\/p>\n

En magnetventil som h\u00e5llit i 9 000 timmar och fortfarande verkar vara p\u00e5 banan. Felet \u00e4r n\u00e5gon annanstans..<\/figcaption><\/figure>\n

R\u00e4tt fel<\/h3>\n

Efter bakslaget s\u00e5 fortsatte fels\u00f6kningen, men innan fler uteslutningar gjordes p\u00e5 diverse kablar och uppv\u00e4rmningssystemet s\u00e5 gjordes en annan grej.\u00a0<\/strong>En inte helt ovanlig grej som h\u00e4nder n\u00e4r det \u00e4r s\u00e5 kallt som det varit \u00e4r att sj\u00e4lva pumpenheten fryser s\u00f6nder. Det har av n\u00e5gon anledning inte varit tomt p\u00e5 Ad-blue i systemet som det ska vara och det har d\u00e5 frusit s\u00f6nder. S\u00e5 det k\u00e4ndes lika bra att kolla detta, \u00e4ven om det inte var detta felkoderna visade p\u00e5. Det brukar visa sig ganska snabbt n\u00e4r man tar loss kontakten till enheten, rinner det ut Ad-blue ur den d\u00e5 s\u00e5 \u00e4r det trasigt p\u00e5 insidan…. Det forsade ut Ad-blue n\u00e4r jag drog ur kontakten, s\u00e5 felet var helt pl\u00f6tsligt lokaliserat och sj\u00e4lvklart. Synd att jag inte gjorde detta tidigare… Som tur var s\u00e5 hade Lantm\u00e4nnen en utbytes enhet liggandes s\u00e5 det var bara att hopp i bilen och fara iv\u00e4g. N\u00e4r pumpenheten sedan kom hem s\u00e5 var traktorn ig\u00e5ng efter 15 minuter… Synd som sagt var att detta inte gjordes tidigare, hade sparat en hel del tid.. Nu g\u00e5r den i alla fall och det \u00e4r sk\u00f6nt. Hoppas att det var sista strulet med Ad-blue f\u00f6r i \u00e5r, eller helst f\u00f6r alltid..<\/p>\n

\"\"
Det d\u00e4r \u00e4r egentligen en elkabel och inte alls en ledning f\u00f6r Ad-blue, s\u00e5 att det rinner ut Ad-blue n\u00e4r den tas is\u00e4r \u00e4r ett tydligt tecken p\u00e5 att det \u00e4r n\u00e5got som \u00e4r galet…<\/figcaption><\/figure>\n
\"\"
P\u00f6l med Ad-blue.<\/figcaption><\/figure>\n
\"\"
En himla tur att det fanns en fungerande att f\u00e5 tag p\u00e5 direkt. Det r\u00e4knade jag inte alls med.<\/figcaption><\/figure>\n
\"\"
Tre skruvar och n\u00e5gra snabbkopplingar senare satt den fungerande enheten d\u00e4r.<\/figcaption><\/figure>\n
\"\"
Sen kunde 720:in rulla ut ur verkstaden ren fr\u00e5n felkoder och fullt fungerande.<\/figcaption><\/figure>\n

Jag kan inte se in i framtiden, men om jag skulle f\u00e5 gissa s\u00e5 sitter jag inom snar framtid i en traktor och plogar sn\u00f6. Det k\u00e4nns just nu som en r\u00e4tt kvalificerad gissning..<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"
