APPENDIX A BATTERY TEST PROCESS
It is recommended t hat this tes t is conduct ed at leas t 24 hours after t he vehi cl e engine has been run or t he batt erycharged to avoi d the need of s urface charge removal or i f thi s t ime cons traint is unaccept abl e due t o circums t ances , thenconduct the charge s t ri p removal process .
Part 1 - Surface Charge Removal
• NOTE: Before carryi ng out a batt ery t est you must ens ure t hat there is no bat t ery s urface charge present .
• NOTE: The batt ery may be t es t ed eit her on a bench or on t he vehicle.
In the cas e of on-vehicle tes ti ng, t he batt ery must be is olated from t he vehi cl e by removal of t he bat t ery negati ve(-) cable from the bat tery t ermi nal before t he measurement is t aken unl ess the vehicle has a transi t rel ay fi tt ed oris in t rans it mode.
A vehicle which has had it s batt ery charged or been dri ven in a 24 hour period before t he tes t , must have i ts s urfacecharge removed us ing one of t he fol lowi ng methods :
1. If 24 hours have pas s ed s ince the las t ti me t he engine was run or the bat tery charged, proceed t o `Part 2 - Bat teryTest '.
2. Turn on t he i gni ti on. Swi tch on t he headlamps on hi gh beam for a mini mum 3 minut es .
3. Swit ch off t he headl amps . For vehi cl es tes t ed aft er t he t rans it relay has been removed, di s connect t he batt ery byremoval of the negati ve (-) cabl e. Vehi cl es wit h a trans i t relay fit t ed or wit h a l ow current t rans port mode enabled do notneed to have t he batt ery di s connect ed.
4. W ait a maximum of 5 mi nut es before recordi ng tes t res ult s for any bat tery measurements .
Part 2 - Battery Test
• NOTE: The batt ery s urface charge mus t be removed before t his t est i n accordance with the procedure in Part 1 above.Ensure t hat t he batt ery terminal connect ors are clean. W hen connecti ng t he Midt ronics t est ing equipment , connect the REDclip to the pos it ive (+) batt ery terminal fi rs t, and t hen connect the BLACK cl ip t o t he negat ive (-) bat tery t ermi nal . Rockt he cl ips backward and forward to ens ure a good connecti on to the bat tery.
• NOTE: Mi dt roni cs 393, 394. 493 and 494 t es ters mus t not be us ed t o t est AGM batt eri es as thes e t est ers are not capableof correctl y t es t ing AGM batt eries and can gi ve an incorrect resul t. For AGM batt ery tes ti ng us e the EXP1080 t es t er or t heGR1 Di agnos ti cs charger.
CAUTION: DO NOT connect t he t es t er to any ot her ci rcuit or chas s is poi nt ot her than t he batt ery negati ve terminal.
1. Att ach the Midtronics tes t er t o t he batt ery.
2. Fol low the i nst ruct ions on t he tes t er t o t est the bat tery. Ens ure t he correct batt ery type and s ize i s s elect ed.
3. Perform the acti on based on the t es ter res ult s (s ee table bel ow).
4. Ent er the readings and t es t code obtained on the Bat tery Report Form (Appendi x B) or equi val ent whi ch records as ami ni mum the t echni ci an's name, Vehi cl e Ident ificati on Number (VIN), Dat e of check, Midtronics code and Bat t ery Volt agefrom the Mi dtroni cs tes ter.
At t he end of the t est , t he bat t ery negati ve (-) cabl e s houl d be re-att ached to t he batt ery terminal.
T EST ER RESULT SACT ION
GOOD BATTERYReturn t o s ervice.
GOOD RE-CHARGEFully charge bat tery and ret urn to servi ce.CHARGE AND RE-TESTFully charge bat tery. Remove s urface charge. Re-tes t batt ery. If s ame res ult repl ace bat tery.
REPLACE BATTERY OR BADCELL BATTERYVeri fy s urface charge removed. Dis connect bat tery from vehicle and re-tes t. If res ult repeat saft er surface charge removal , replace batt ery. DO NOT RECHARGE.
