I have a Suzuki Swift 1.0 Gls 1998 and the earth recently snapped which i have had fixed but before it was fixed i didnt know what was wrong with it so i tried to jump start it and not i have had it fixed the rev. fuel and temp. gages dont work, i was wondering if this was a common problem and also if this has happened to anyone or if anyone know what the problem may be and how i can get it fixed.

cheers
