The onboard charger detects how much charge is in the battery but it's designed to charge at no more than 90% of the battery capacity to avoid gassing of the battery. Therefore if you have hotwired a standard battery charger which is not the right toool for the job then it could possibly do some damage especially if the battery isn't holding a charge which could cause the battery to explode if it doesn't cut the full current before reaching a 100% charge. You need to replace the onboard charger with the same rating charger if the original one is defective which seems to be the case after you have checked it with the multi-meter.
