# حركات patterns between the perfect and imperfect

I am trying to understand whether there is a pattern in the حركات corresponding to perfect and imperfect conjugations of Form I verbs. Is this true:

1. When there is a كسرة under second letter of the root in the perfect, there will be a فتحة over the second letter of the root in the imperfect. Examples:
 Imperfect Perfect Meaning يَسْلَمُ سَلِمَ Be safe and sound يَضْمَنُ ضَمِنَ Guarantee يَعْلَمُ عَلِمَ Know يَفْشَلُ فَشِلَ Fail يَقْبَلُ قَبِلَ Accept, approve

2. When there is a ضمّة over the second letter of the root in the perfect, there is a ضمّة over the second letter of the root in the imperfect. Example:
 Imperfect Perfect Meaning يَكْثُرُ كَثُرَ Multiply, increase

3. When there is a فتحة over the second letter of the root in the perfect, the حركة corresponding to the second letter of the root may be a ضمّة, فتحة or كسرة (no pattern). Examples:
 Imperfect Perfect Meaning يَحْصُلُ حَصَلَ Obtain, procure يَصْنَعُ صَنَعَ Make, manufacture يَطْلُبُ طَلَبَ Demand, request يَعْمِدُ عَمَدَ Baptize يَفْتَحُ فَتَحَ Open يَكْتُبُ كَتَبَ Write يَكْفُلُ كَفَلَ Guarantee, sponsor يَنْزِلُ نَزَلَ Descend, dismount

#1 is usually the case, but there are exceptions. The rest is right.

Can you provide an example of when #1 is not the case (i.e., there is a كسرة under the second letter of the root in the perfect, but not a فتحة over the second letter of the root in the imperfect)?
